Know how to use hexadecimal numbers or else computers will confuse you.
There are different bases for numbers. One of these bases is base-16 which is often times referred to as hexadecimal. This number format is used often in computer memory addresses and for HTML it is a way to define colors.
The base-16 numbers are peculiar. They do not work like base-10 numbers or “normal” numbers. instead of counting to 9 they count to 16.
There are not 16 single digit numbers to count to 16, so instead this number system uses the alphabet for the numbers that it cannot be represented by single digit numbers.
The hexadecimal number system uses the characters A through F. ‘A’ represents the number 10 and ‘F’ represents the number 15. The numbers in-between correspond with the letters that come between A and F.
So, remember when converting anything that comes above 9 as the remainder use the letters to replace those two number numbers.
An example for those who learn by example.
Number: 15 = F
Number: 13 = D
Number: 20 = 14
Number: 170 = AA
