[Blindmath] binary basics

[derek riemer]

As well, Adding, subtracting, ... is the same. We carry the 1 if adding.

2+2

0b10 + 0b10

10
10
--------
100
What I did there is 1+1 is 10 in binary, or 2 in base 10. The 0 gets 
dropped in the 2's place, and the 1 gets carried. Then we add it to 
whatever is in the 4's place, and there you go.
In most real world places, you would convert the binary to hex, and use 
that for addition, because it is simply easier.
