# 'three times as much' vs 'three times more'

My father has three times more money than my mother.
My father has three times as much money as my mother.

Is there any difference in meaning between the above sentences?

Thanks.
Original Post
According to our school's maths teachers, if the mother has 100 dollars:

1)" the father has 3 times more money than the mother " means the father has 400 dollars.

2) "the father has 3 times as much money as the mother" means the father has 300 dollars.

Hope to hear from teachers from this forum too.

Yes, bc has it right. People might say "three times more" when they mean "three times as much" but it usually isn't what they really mean.

If the mother has x dollars, "three times more than x" means 3x + x -- "more than" means "add".

"Three times as much" means 3x.

I think it is worth mentioning that native speakers of English often use/misuse the two terms interchangeably (to mean what bc tan described in #2 above).

When it comes to big numbers,the ambiguity disappears naturally.
A is 1000 times bigger than B
Whatever, 1001B equals, approximately, 1000B

Could somebody help me?

Mengxin means that when we are dealing with big numbers, it does not make a big difference to use one term in place of the other because the result will be almost the same. You know, for example, 1000 is not very different from 1001. However, in your case, the difference between 3 and 4 is noticeable.

Well, I'm not really sure if I could clarify it.

I think Mengxin2009 should clarify. I am still puzzled.

You’re no more than asking me to make a summary of the above posts. Ok, let me present here what I understand about “n times larger than ” vs “n times as much as”.

As above posts have said, “n times larger than” may be understood in two ways, but the correct version is “If A is n times larger than B, then A = (n+1)B”. However, we can’t expect people are always so precise about arithmetic things in daily life, so on many occasions the two terms are used interchangeably.

I think what you are worried about is whether natives will misunderstand the intended meaning if the two terms are used interchangeably, aren’t you? Of course the chances are rare. You know, if the speaker is aware of the possible misunderstanding or needs to make difference about such things, s/he may avoid using the “larger than” thing. On the other hand, seldom would people make great efforts to differentiate 1001 and 1000. Would you?

I am sorry for not amswering your question technically.
