To find the number that must be subtracted from -5 to get 10, you would set up the equation -5 - x = 10, where x is the unknown number to be subtracted. To solve for x, you would first add 5 to both sides to isolate x, resulting in -x = 15. Then, multiply both sides by -1 to solve for x, giving you x = -15. Therefore, the number that must be subtracted from -5 to get 10 is -15.
5 + 5 - 5 + 4 + 1 = 5 x 2 (= 10)
