1. When adding, the decimals MUST line up: 012.3 +32.1 2. When multiplying, you dont have to put the decimals side by side: 12.3 x323.55 Then you count how many numbers are after the decimals, which, in this case, is three. Hope it helped!

usually the largest on the top row of the sum, then the middle, then the smallest, makes a tidier arrangement
