What is 4 times greater than 80?

4 times greater than 80 seems easy enough, but is it?

Let's assume the answer = 320 (since 4 x 80 = 320). Then shouldn't this statement be true?:

320 is greater than 4 x 80.

But that is not true. 320 is not greater than 4 x 80. It is the same!

To make it greater, we could make make a formula like (a+1)b where a=4 and b=80 to get this answer:

(4 + 1) x 80 = 400

But if that is the case, why not simply say "What is 5 times 80?" 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 4 times greater than 80, they mean 4 times as much as 80 which equals 320. We recommend that you ask them to clarify what they mean.
