For example, 2 x 5 x 6.3
7x9=63
The two numbers that multiply to get sixty-three and add up to zero are 7 and -7. This is because 7 × -9 = -63 and 7 + (-9) = -2. The correct pairs, however, are 9 and -9, which multiply to 63 (9 × -7 = -63) and add up to 0 (9 + -9 = 0).
To find what you multiply to get 63, you can consider its factors. The pairs of numbers that multiply together to give 63 are 1 and 63, 3 and 21, and 7 and 9. For example, 7 multiplied by 9 equals 63.
