sums and products

Hi,
what is the most natural way to say these:

Find two numbers whose sum is equal to negative 11.
Find two numbers whose product is equal to 11.


I know I can say "numbers that add up to 11", but I am not sure such structures would work with multiplications, other operations, negative numbers, etc.
"numbers that multiply up to negative 11" ???
I also think I could leave out "up", but I am not sure. Could anyone tell me what structures I could use? Thanks. Emotion: smile

Hi K,

You can just say "whose sum is negative (or minus) 11" or "whose product is 11."

The boldface ones are fine. I would not write out the "negative", though it would be said. "equal to" is optional. "up" and "out" are optional.

Find two numbers whose [sum / product] is (equal to) [11 / -11].
Find two numbers that [add (up) to / multiply (out)] to [11 / -11].

Thanks, I see.
My problem was about that "whose sum/product", which doesn't seem too common on Google in some searches, so it made me wonder. I guess it's just because everyone uses some darn mathematical notation, like "Find two integers N and M such that NxM equals 11".
As for "negative", I wouldn't write it either, as you suggested, but I wanted to make clear I had put something negat

Reminds me of my days solving quadratic equations.

Find two numbers whose product is minus 28 and whose sum is 3...(x-4)(x+7)

I actually enjoyed that. But then, I liked balancing chemical equations too. Once a geek, always a geek.

Hi,

We also, at least where I live, say informally
Find 2 (or more than 2) numbers that come to 11 or that make 11.

Not necessarily just though addition, either, but other math operations as well.
