What is Hex?
Hex or Hexadecimal number system works similarly to the binary and the decimal systems. The numbers 10 or 2 as a base are not considered, the number 16 as a base is used. Hexadecimal number system considers 16 digits consisting of the number 0 to 9. It also uses the alphabets A, B, C, D, E, and F to denote the numbers from 10 to 15. The idea of the Hexadecimal number system is based on the concept of making the bigger binary number small and easy. Thus, each digit of it signifies 4 binary digits, known as nibbles. It may be surprising for you to know that the numbers 1010101010 can be described as 2AA in this system. In the case of computer systems, the greater binary numbers are reduced so that they can quickly be changed from one system to another.
From Hex to decimal & Hex to Decimal
Changing from the decimal system to the hex system or vice versa is related with the multiple number systems having place values. But, the changing of values from hex to decimal or the other way round is like changing the values from decimal to binary or vice versa. Already discussed earlier, the number 16 is used as a base in hex. So, when considering the value 2AA, a power of number 16 is used as place value. The letter ‘A’ is considered as ‘ones’ or 160. The second alphabetical letter which is also "A", from the right-hand side, indicates the value 161. The number 2 is equal to 162. You must know that the alphabet "A" in the hex system is the same as or equal to the number 10 in the decimal system.

How the addition is done?
Hexadecimal number system considers the same concept of the addition of the decimal system. However, the numbers being represented by the alphabetical letters A,B,C,D,E, and F. The addition system in Hex is based on computing the basic addition of decimal at the same time transforming from hex system to decimal system when the values greater than the number 9 is available. Hex addition example is given below:
How the subtraction is done?
The system of subtraction in Hex is similar to the process of addition. But, when the borrowing is done in Hex “1” which is borrowed denotes 16decimal and not 10decimal. So, the column from which it has been taken is 16 times more than the column from which it has been borrowed. The conversions and computations of the alphabetical letters A, B, C, D, E, and F are performed properly, the subtraction process is not at all difficult when compared with the decimal subtraction. Hex subtraction example is given below:
Hexadecimal addition calculator can help you in hex addition for a quick calculation.
How the multiplication is done?
The multiplication performed in the Hex decimal system can be a bit twisty because when the computations are done from the hex system to the decimal system involve more attention and care because the numbers are of greater value. Hex multiplication example is given below:
How the division is done?
The greater calculations in the hex system are similar to the greater calculations of division in decimal. The users can compute to decimal and carry out greater calculations of division in decimal, then it can be computed back again from where it was started. Please, see an example of hex division below:
Hexadecimal calculator is used for hex addition, hex subtraction, hex multiplication, and hex division without pen and paper. Hex adder calculator is an effcient tool for adding two hex values. Similarly, hex calculator can easily calculate two given values into 4 different calculations i.e., multiplication, division, subtratction, and addition. Hex to binary and binary to hex converter can be used if you want to convert numbers to hex instead of calculating them
1This calculator will help you make a decision between two credit card offers. First enter a sample balance amount for the comparison and a monthly payment that is greater than the monthly interest charge.
From there, fill in the fields where necessary. Under both the columns for Card #1 and Card #2, input the following information: annual fee, introductory annual interest rate, the term of that introductory rate, and the regular interest rate. Then from the pull-down menus provided, choose either “daily” or “monthly” as the compounding periods. Press CALCULATE, and you’ll learn the number of payments it will take to pay off the balance on both cards, and you’ll see the total costs associated with the balance on the two cards.

How to Find The Right Card
Wallet With Credit Cards.
It seems every week there's a new, shiny credit card offer in the mail. From free airline miles, to cash back, to credit towards vacation and free gas, how do you tell the difference between a great value and a scam? While there is no blanket perfect card for everyone, there is the perfect card that best suits your needs. There are three components that go into making a good decision on your next credit card. The details of the credit program, the rewards, and your spending habits create the ideal card for you.
Since you can't select "cafeteria style" what best suits your needs based on credit, rewards, and spending habits, you must look at the offerings in each group and choose the best all-around based on your needs. The first step in selection is thinking about spending habits.
Analyze Your Spending Habits
Analyzing your spending habits is essential to finding the right card for you. It's important that you are honest about those habits and not base your assessment on the person you'd like to be, or intend to be, going forward. A good assessment includes asking yourself:
How much do I charge every month?
Do I carry a balance? All the time or just occasionally and then it's paid off?
What types of charges do I make most?
How often do I charge?
What's my credit score?
Do I have multiple credit cards?
How often do I travel?
Am I brand loyal?
Drawing a realistic picture of your spending habits will help you pick out a card that best suits your needs. The amount you charge every month is important. Some credit card companies offer amazing perks to high spending customers. If you fall into that group, you could be rewarded for your expenditures, but if not, you might pay a higher yearly fee.
Some cards also offer rewards if you spend a certain dollar amount within the first six months of the account being open. If you don't intend to spend that amount, the card may not be worth it.
If you carry a balance
For credit card customers who consistently carry a balance, it's better to look for low-interest rates than miles or other perks. The discounts you receive from the card won't prove worth the extra dollars you spend on the interest and fees for carrying a balance.
Know the types of charges you make most
Knowing the types of charges you make most often is important when looking at the different benefits of the cards. Most rewards cards offer benefits on the dollars spent in a particular category. For instance, a card may give you two percent cash back on all gas and grocery expenses and one percent on all restaurants. If you never charge groceries or gas, this is obviously not the right card for you. Pair up your spending with card benefits for maximum reward.
Why your credit score matters
Credit card companies advertise a lot of deals as an incentive to draw in new customers. However, many of the rates you see and the best offers require a minimum credit score. If you don't qualify for that score, your interest rates will be higher.
Also, must credit card companies reserve the right to increase your interest rate should you miss a payment or should your credit score plummet, even if you keep making your payment to them on time. Many of the companies tightened up their policies and penalties during the recession.
Multiple cards make a difference
If you have multiple cards, you're probably dividing your spending among them, which means you may not be eligible for the spending minimums that will give you the best benefits.
While this is sometimes a good idea -- like when you place your gas spending on the card that gives you the most benefit for doing so, and your travel expenses on the card that rewards those at the highest level -- it takes a good memory to manage which card offers the best deal on which type of expense.
When travel cards make sense
If you don't travel often, or don't spend your time at a particular type of hotel or on a single airline, travel cards will not benefit you. Be honest about the type of traveling you do, how you get there, and where you stay. Being brand loyal pays from a rewards standpoint but if you're a bargain traveler, going with the best deal, not the same brand, a loyalty card won't be your best bet.
Anatomy of a Credit Card
Now that you know a little more about your spending habits, it's important to discuss the particulars of cards and what makes them different.
Read the fine print on your card offer to find out if the card you're considering has an annual fee. If it does, and many of the high paying benefit cards do, do a quick calculation of how much you would need to see as a return for it to be worth it. Some cards will waive the fee for the first year so if you're unsure of whether the fee will cover the benefit, you can try it for a year and cancel if it doesn't.
Many credit card companies have cards with and without fees, so if you find a company you want to do business with but don't want to pay an annual fee, ask a member of their customer service team what options they can offer.
All credit card companies are going to charge you something for not paying off what you owe each month. The only exception to this is balance transfers and introductory rates. Read the fine print of the offer to find out:
what the interest (APR) rate is
how long the interest rate is in effect
if the balance transfer rate is the same as the interest rate and for how long
The importance of paying on time
As mentioned above, credit card companies will raise your rates if the minimum due is not paid each month. A good deal on an APR or introductory rate can be negated instantly with one late bill. Make sure you know the company's policy on late payments and its effect on rate increases before applying for the card.
In addition to the rate, it's important to understand how the company calculates the interest charged on late payments since it can make a significant difference. You will pay less if you select a company that bases the balance computation method on an average daily balance and not on the balance of two billing cycles.
Sign-up bonuses and the aftermath
Sign-up bonuses are wonderful if you can meet whatever spending level required and the card (after the bonus) fits your spending habits.
Hidden fees are real
While hidden fees aren't entirely hidden -- they're always in the small print -- many credit card customers don't take the time to read them. If you're considering a new card, acquaint yourself with these charges if you want to avoid overpaying.
Understanding credit limits and utilization rates
When you've been approved for a card, you'll be given a credit limit. This is an amount of credit the company is willing to extend you. Many credit card companies will continue to raise the limits for card owners with good credit who pay on time. This is a benefit that can help your credit score, as long as you're not using a large percentage of the increase.
Credit score companies factor in your utilization rate, which is the percentage of your open credit in use. They do this for each card as well as the total for all of your cards. The ideal utilization rate is 20 percent (or lower). For instance, if you had a $3,000 limit on your card, keeping your balance at (or under) $600 would help increase your credit score. It shows lenders you have been extended to a higher line of credit but show the restraint not to use it.
Chip cards and what they mean for fraud
Identity theft and credit card fraud are major concerns for credit card holders and the companies that extend them the credit. Many companies are starting to embed chips in their cards to fight identity theft and fraud. The U.K. is already using chip and PIN cards, but the U.S. has been slow to adopt them. The new cards are not compatible with current card readers.
The new cards employ pins instead of signatures, so even if someone stole the number of the card, she would need the pin to complete the transaction. The cost to switch to a new system so far is prohibitive, but this is something that might show on the horizon for the United States. You should consider this in choosing a card if you travel a great deal in Europe, as some U.S. cards will no longer work there.
Assessing the Rewards
Not all rewards programs are created equally. Your spending habits should influence your choice in reward cards. There are many options out there including:
Travel rewards cards
Travel rewards cards are cards that offer direct seats on a particular airline. These cards are ideal for brand loyal, frequent travelers with frequent flyer accounts.
Key point of these cards is that they not only lock you into traveling on a specific airline, but they also employ blackout dates (times in which you cannot travel) and offer only a limited number of seats. You must book early if you're using miles.
Another problem consumers have met recently is the number of changes companies offering frequent flyer programs have instituted. Companies like United and Southwest are now basing rewards on ticket cost, not on distance. If you get a great deal on a ticket, you'll earn less as a frequent flyer. Keep this in mind when you are considering a travel reward card.
Some travel cards pay rewards as credits against travel. This means you pay for your ticket first and get credited on your bill, a nice perk that helps avoid blackout dates and provides more flexibility.
Cash back cards
There are a number of cash back reward cards that give you a portion of your spending back. Look for cards with high total percentages or high rewards in the area you spend most. A few of these cards don't give direct cash rewards back but rather add them to an investment vehicle for you. Understand how the reward is paid before choosing one.
Gas rewards and company-specific cards
These reward cards are similar to the cash back but offer rewards with a specific company or category pay out, such as earning free gas or merchandise. As with all rewards cards, the interest rates are higher, so they are best for people who do not often carry a balance. Also, reward levels change so make sure you understand what you're getting and there's more about the card you like than simply the reward agreement.
Things to Know
Now that you have a better understanding of yourself as a credit card user, and the kinds of cards and rewards on the market, don't apply for every card that looks good. Several credit card applications in a small period of time could make your FICO score drop slightly when multiple inquiries appear.
If you get a pre-approved credit card offer, you can still be denied. These companies only have a broad idea of what your score is on the credit card spectrum. When you apply and they check your real credit score, you might get rejected.
Doing your research can help you find the best offer. You don't have to wait for it to find you. Read the reviews and compare numbers.
Putting it all Together
While finding the perfect credit card for you means being honest about who you are and what you need now, it's also important to review your needs periodically, as they change with lifestyle and debt level. Don't forget to check your card benefits quarterly. Lenders have the right to make changes to these as well.
