What is 15 times greater than 8?

15 times greater than 8 seems easy enough, but is it?

Let's assume the answer = 120 (since 15 x 8 = 120). Then shouldn't this statement be true?:

120 is greater than 15 x 8.

But that is not true. 120 is not greater than 15 x 8. It is the same!

To make it greater, we could make make a formula like (a+1)b where a=15 and b=8 to get this answer:

(15 + 1) x 8 = 128

But if that is the case, why not simply say "What is 16 times 8?" instead of saying "times greater than?"

We do not think there is a correct answer, because the question can be misinterpreted.

It seems that when many people write 15 times greater than 8, they mean 15 times as much as 8 which equals 120. We recommend that you ask them to clarify what they mean.
