F to C: Deduct 32, then multiply by 5, then divide by 9 C to F: Multiply by 9, then divide by 5, then add 32
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).

The two numbers that multiply to 45 and add up to -14 are -9 and -5. This is because (-9) × (-5) = 45, and (-9) + (-5) = -14.
1-9
The two numbers that add to get -2 and multiply to get 9 are -3 and -3. When you add -3 and -3, you get -6, and when you multiply them, you get 9. This is because -3 + -3 = -6 and -3 * -3 = 9.
