is what?

There are only 10 (base2) types of people in the world: those who understand binary and those who don’t. Decimal to Binary: What is the largest power of two that will go into our number? no yes 5 -4 = 1 noyes no yes = = = 22-2 = = 114

19 Decimal to Binary: What is the largest power of two that will go into our number?

Binary Addition: 0 plus 0 = 0, 1 plus 0 = 1, 1 plus 1 = 10 (two)

Binary Addition Remember: = = = = 11
