What is 40 times greater than 21?

40 times greater than 21 seems easy enough, but is it?

Let's assume the answer = 840 (since 40 x 21 = 840). Then shouldn't this statement be true?:

840 is greater than 40 x 21.

But that is not true. 840 is not greater than 40 x 21. It is the same!

To make it greater, we could make make a formula like (a+1)b where a=40 and b=21 to get this answer:

(40 + 1) x 21 = 861

But if that is the case, why not simply say "What is 41 times 21?" 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 40 times greater than 21, they mean 40 times as much as 21 which equals 840. We recommend that you ask them to clarify what they mean.
