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. :)
