Powers of ten!
1. Count the zeroes in your powers of ten (ex: 10 has 1 zero, 100 has two zeroes, etc.)
2. Move the decimals as many places as you counted in number 1!
- If it is multiplication, the decimal moves RIGHT because it's getting bigger!
- If it is division, the decimal moves LEFT because it's getting smaller
