Yes.
It can be very helpful, so the question is inappropriate.
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!
It was 1 241 177 300 000 decimals in 2002
it affects because when you multiply you have to move the decimals to the left or right.......(helpful info)

It is important because depending on the problem it is easier to use fractions or decimals. Sometimes the problem is asking for an exact answer, in which case you would keep it in fraction form.
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. :)
The fact that we count in tens. This is due to the fact that we have ten digits on our hands.
It can be helpful for people who do not have a clue where the decimal point should go in the answer. For those who do know, the exercise is pointless.
By a power of ten.
