Hexadecimal System (Hex System)
The hexadecimal system, often called the hex system, is a way of counting and representing numbers just like our everyday decimal system. However, it uses 16 different symbols instead of 10. In the decimal system, we use the digits 0 to 9. In the hex system, we use the digits 0 to 9 just like in decimal, but we also use the letters A, B, C, D, E, and F to represent the numbers 10 to 15.
So, in the hex system:
 0 stands for zero
 1 stands for one
 2 stands for two
 …
 9 stands for nine
 A stands for ten
 B stands for eleven
 C stands for twelve
 D stands for thirteen
 E stands for fourteen
 F stands for fifteen
To write numbers in the hex system, we simply combine these symbols. For example, if you see the hex number “1A,” it represents the decimal number 26. Hexadecimal is often used in computing because it’s a convenient way to represent binary data (0s and 1s) in a more humanreadable form.
Decimal System
The decimal system, also known as the base10 system, is the way we count and represent numbers in our everyday lives. It uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Each digit in a decimal number represents a different power of 10. The rightmost digit represents “ones,” the next one to the left represents “tens,” the next represents “hundreds,” and so on. This means that when you move one place to the left, you’re multiplying the number by 10.
For example:
 The number 123 means 1 hundred, 2 tens, and 3 ones.
 The number 4567 means 4 thousands, 5 hundreds, 6 tens, and 7 ones.
The decimal system is widely used in our daily lives for counting, measuring, and performing arithmetic operations. It’s the most common number system in the world.
5 Fun Facts about Hex and Decimal Numbers
 The word “hexadecimal” comes from the Greek words “hex” (meaning “six”) and “deca” (meaning “ten”). This reflects the fact that hexadecimals use a base of 16, with the digits 09 representing the values 09, and the letters AF representing the values 1015.
 In hexadecimals, the letters AF are often used to represent the values 1015 because these letters are easy to distinguish from the digits 09. This makes hexadecimals a more readable and userfriendly way to represent large numbers.
 One of the most famous uses of hexadecimals is in the HTML code that is used to create websites. In HTML, colors are often represented using hexadecimal codes, with each of the red, green, and blue values of the color being represented by a pair of hexadecimal digits.
 Many computer games also use hexadecimals to represent values such as colors, terrain types, and character attributes. This allows developers to store large amounts of data in a compact and easily readable form.
 In mathematics, hexadecimals are often used to represent very large numbers that would be difficult to read and work with using traditional decimal notation. For example, the number FFFF in hexadecimal represents the much larger number 65535 in decimal.
5 Benefits about Hex and Decimal Numbers
 Compact representation: Hexadecimals allow large numbers to be represented using fewer digits than would be required in decimal notation. This can be especially useful when working with large amounts of data or when space is limited.
 Easier to read: Because hexadecimals use a combination of digits and letters, they can be easier to read and distinguish from one another than long strings of digits in decimal notation.
 More userfriendly: Hexadecimals are often used in computer programming and other technical fields because they are easier for humans to read and understand than binary or other lowlevel representations.
 More efficient: Hexadecimals can be more efficient to use in certain contexts, such as when working with large amounts of data that need to be stored or transmitted.
 Widely used: Hexadecimals are used in a variety of fields, including computer programming, web development, and data storage, which means that they are a useful skill to have in many different professional contexts.
5 Funny Jokes about Numbers
 “Why was the math book sad? Because it had too many problems.”
 “Why was 6 afraid of 7? Because 7 8 9.”
 “I tried to calculate how many sheep there were in Wales, but I kept getting Wales is not sheep.”
 “Why did the tomato turn red? Because it saw the salad dressing!”
 “Why was the number 4 unhappy? Because it was two squared and didn’t want to be squared away.”
What is a Hexadecimal Number?
A hexadecimal number, or “hex” number for short, is a base16 number used to represent larger integers in a more compact and convenient form.
The Base16 Numbering System
The base16 numbering system, also known as hexadecimal or simply hex, uses 16 distinct symbols: the digits 0 to 9 and the letters A, B, C, D, E, and F.
Uses of Hex Numbers
Hex numbers are often used in computer programming and data storage because they are more efficient than the base10 numbering system that we use in everyday life. For example, a single hex digit can represent 4 bits of binary data, which allows for more compact representation of large numbers. This can be especially useful when working with large amounts of data or when communicating with devices that use binary representation.
Notation of Hex Numbers
In order to distinguish hex numbers from other types of numbers, they are usually prefixed with “0x” or a dollar sign “$”. For example, the hex number 0xFF would represent the decimal number 255, while the hex number $FF would represent the same value.
Converting Between Hex and Decimal
To convert a hex number to decimal, you can simply use a calculator or online converter tool. Alternatively, you can manually convert the number by multiplying each digit by the corresponding power of 16 and adding the results together.
Converting from decimal to hex is slightly more complicated, as it involves dividing the decimal number by 16 and keeping track of the remainder until the quotient is zero. However, there are also calculator tools and online converters that can make this process easier.
Conclusion
In summary, a hexadecimal number is a compact and convenient way of representing large integers in the base16 numbering system. It is commonly used in computer programming and data storage due to its efficiency, and can be easily converted to and from the base10 numbering system that we use in everyday life.
