You line up the decimals with the thousandths and put the decimal straight down from where it is and just add with the decimal in the same spot.
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!
line up the decimals together
your dumb if you don't know how to round decimals on a number line
You need to line up decimals for additional and subtraction. For multiplication, you don't need to line them up - in fact, it would serve no useful purpose.
Adding and subtracting decimals is easy. When you put the numbers one above the other, line up the decimals vertically and treat as you would any whole number just keep the decimals in line and bring it straight down to your answer.

Hey awesome Question. The answer is no you do not have to line up the decimals when multyping only when adding and subtracting. The main thing is when you multiply make sure you put the decimal in the right place in your answer. YOu count how may places their are behind the decimals in BOTH numbers then you make sure their are that many places behind the decimal in you answer. :)
