How would you phrase this ?

For the sum (10 - 2)
Would you say
A) "What is 2 takeaway from 10?"
Or
B) "What is 10 takeaway 2?"

B

C) what is 10 minus 2

It’s helpful for kids learning maths to hear it both ways, so with the kids I would vary how I say it.
with An adult I’d say “10 minus 2”

I would say (b). Or "ten minus two."

The version given in (a) sounds odd to me - I'd expect it to be "2 from 10" if used at all - I'd assume not a British speaker, tbh. Or if it's children being introduced to the idea I might ask "what is 2 less than 10?"

10 take away 2
Or what is 10 subtract two
Or 10 minus two.

10 subtract/takeaway 2.

Sorry to be pedantic, but it’s not a sum 🫣

I needed to point out it wasn't a sum either.

I would use different language depending on who I was speaking to.

10 minus 2 (or subtract 2 from 10).

10 minus 2

10 minus 2 or 10 take away 2.

I'd never say 2 takeaway from 10. It sounds grammatically a bit weird and also takeaway wouldn't be all one word in this context.

I might say take 2 away from 10 though - that makes more sense!

Depending on the age of the person doing the sum, I might say:

If you have 10, and you take 2 away, how many do you have left?

I would call it a "sum"... the sum of 10 and -2...
If I was just asking someone in a conversation then (B) is better.
You could say 2 taken away from 10.
Depends on who you were asking and how awkward you wanted the question to be! Some maths puzzles are about interpretation more than the actual act of doing the maths.

B

As PP says, C) 10 minus 2

I’d say “10 minus 2”; possibly 10 take away 2 if speaking to a very small child?

Well option A is grammatically incorrect so it wouldn’t actually be helpful for children to hear it!

10 minus 2. Minus isn’t a difficult word to learn even for small children.

"what is 2 take away from 10?" makes no sense.

That would be "what is 2 taken away from 10?" but it's a very clunky way to ask what 10-2 is.

But two away from ten could be eight or twelve, depending on context.

Its ten minus two or ten subtract two. Possibly two subtracted from ten.

2 takeaway from 10 could not be 12, what you've put was never in the OP

2 away from 10 yes that could be 8 or 12.

B

Please don't call it a "sum"
Sum means add.

It can be a sum. It is the sum of 10 and negative 2.

In primary school maths, questions like this would be referred to as 'sums'
