How to multiply two numbers that are not close to each other?

It’s possible to multiply two numbers that are not close to each other by using two reference numbers. Eight is close to 10, so we will use 10 as our first reference number. 27 is close to 30, so we use 30 as our second reference number. From the two reference numbers, we choose the easiest number to multiply by.
