Sorry, being pedantic here, but it's a pet hate.

If you say something is 20 times less. It means you take the original value and multiply it by 20, then subtract the new value from the original. This will always give you a negative value.

x-(x * 20)

What you want to say is that it's one 20th of the original value :)




"20 times more: 20 * x"

"20 times less: x / 20"


I wish the English usage matched the math usage. Sadly, it does not.

20 * x is "20 times as much" but only "19 times more", IMO.
