#### What is HEX ?

**HEX** is a number system with a base of **16**. This number system is used in computers because it is easy to convert between binary *(the number system with a base of 2 that computers use)* and hexadecimal. In the **HEX** system, each digit can represent a value from *0 to 15*. The first ten digits *(0-9)* represent the numbers* 0-9* normally, while the last six digits *(A-F)* represent the values *10-15*. To convert from HEX to decimal, simply multiply each digit by its place value and add up all the results. For example, the HEX number 3C7 would be equal to 3*16^2 + 12*16^1 + 7*16^0 = 951 in decimal.

#### What is Decimal ?

**Decimal** is the base **10** number system, which means that it uses **10** digits *(0 – 9)*. It is our standard counting system, and is used worldwide. The **decimal** system is often called **“denary”** or **“dec”** for short.

When we count in **decimal**, each digit has a value **10** times that of the digit to its right. So the number **123** means *1×100 + 2×10 + 3×1*.

The number **0 **is special, because it denotes the absence of any quantity. So *123* means one hundred and twenty-three, but *1230* means one thousand two hundred and thirty.

The value of each digit also depends on its position in the number. In *123*, the *3* has a value of *3 (1×1)*, but in 1230 it has a value of *300 (3×10²)*. This is why *1230* is ten times as big as *123* – each digit is moved one place to the left, and its value increases tenfold.
