Did you know that there are other systems of numbering other than our standard decimal system?
The first numbering system was base 60.
The decimal system, or base 10, is in mathematics and everyday life, but computers and other electronics need to have simpler (sometimes more complex) systems. Enter, binary.

Step 1: Hex Decimal
ok hex decimal is like real counting but it uses numbers and letters.
the numbers 1-20 using hex decimal:
as you can see it uses the letters a-f to repesent real numbers.
so every time you get to nine you go to a and so on. so 100 in hexdecimal is 64.
hex decimal is usely used in video games becauses you can fit big numbers in small space.
Step 2: Binary
binary in the hardest to comprehend. it uses ones and zeros to repesent numbers. here are the numbers 1-20 in binary.
all the ones and zeros repesent powers of 2. the first one = 1.the second one = 2. the third one = 4 , and so on and so on.
so 3 = 11 in binary. because 1+2 = 3
