Given A=9 and B=3, which of the below exactly give(s) the mathematical relation between A and B?
1. A is three times as much as B.
2. A is three times more than B.
3. A is twice more than B.
According to my knowledge from grammars, 1 and 3 both work well. But some of my colleagues point out that they were told 1 and 2 correct by their foreign teachers.
Who is correct? Thanks a lot.

For me, "A is 3 times B". Mind you, I was no maths whizzkid at school!

How can 3 be correct? Do you know the meaning of "twice"?

I can see some skewed logic with 3, given that it says "twice more". If you take the number 3 and add it to itself twice, you get 9!

Skewed logic indeed!

Twice means two times, right?
So, you uphold 1 and 2?

What do you mean "skewed logic"? I can't fathom it.

Two times the original = twice
Added to the original = more

Not saying I agree, but that is the thinking.
