Multiplying by 5s

One of the easiest numbers in the times table is 5. When first learning to multiply numbers by 5, it is easier to remember a helpful trick instead of memorizing all of the outcomes. First off, if the number you are multiplying 5 by is even, then the last digit will always end in a zero. If the number you are multiplying 5 by is odd, then the last digit will always end in a five.

This quick fix will help with multiplying even the largest of numbers.
