Quick Maths Language question

[TheFurryMenace]

Im helping my daughter with some extra maths as she's struggling, I came across a term I dont understand. What does the following mean?

Q - Increase 17 by 8.

Does that mean add or multiply?

Thanks

Add

Add.

Add

You’ve never heard of ‘increase’? That can’t be true!

I expect it was the 'by' that did it. We say "times by" and "multiply by" and "increase by a factor of" which are all multiplication sums. So "increase by" sounds like it has just missed off a word or two. But it is definitely an addition sum.

@GeorgieTheGorgeousGoat it's the 'by,' not the increase.

Increase = add.

Thanks all. Georgia, they did not use that term when I was a child, so no, I wasn’t sure. Sorry if that offended you in any way.

No, I don't think you have offended anyone. It's hard to know what kind of term they use these day, unless you are up to date with education. Especially someone foreign like me have no clue what the word means sometimes.

You can also ‘increase by’ a % or fraction and neither of those would be addition either.

I wouldn’t be surprised if ‘increase’ as addition was it’s least usual use in a maths question.
