Ineed .. so can somebody me ? what two number and get 10 and -24 ?

What 2 numbers do you multiply to get 10? In other words, what number can you multiply with another number to get 10? 

The formula to solve this would be:

X x Y = 10

There are at least two combinations of two numbers that you can multiply together to get 10.

For your convenience, we have made a list of all the combinations of two numbers multiplied by each other that will make 10:

1 x 10 = 10
2 x 5 = 10
5 x 2 = 10
10 x 1 = 10 

The answer is 10 because how I did it was I subtracted 24-10=10and that's how I know the answer
