Question

What numbers multiply to make 16 and add to give you 16

Answer 1

You can multiply 8 and 2 and that gives you 16. And you can add 8 twice and that also gets you 16.

Answer 2

There are no numbers that multiply and add to give you 16
If you mean to make the questions individually then the factors of 16 are 1,2,4,8,16 so you can use any of those
the numbers that add to equal 16 are 1,15,2,14,3,13,4,12,5,11,6,10,7,9,8
If there was more to the question just tell me :)
