Find two numbers whose sum is 15 and the product is 36
ycow [4]
The two numbers are 3 and 12.

I got these numbers by factoring 36.

1 * 36    sum : 37
2 * 18    sum : 20
3 * 12    sum : 15

It is easier to find the factor of a number and solve for the sum. Than to find the addends of a number and solve for the product.

There are 9 factors of 36 while 14 addends of 15.
