You can change the order of the multiplicands to give an intermediate answer that is simpler to work with. For example, to calculate 25 * 45 * 40 you could do 25 * 45 = 1125 and then 1125 * 40 = 45000 Or You could do 25 * 45 * 40 = 25 * 40 * 45 = 1000 * 45 and multiplication by 1000 is simply adding three 0s zero at the end, so 45000. Easy.
