Subtract: -10\ -\ (-21)−10 − (−21)

Answer 1

To solve the expression \(-10 - (-21)\), we can follow these steps:

1. Recognize that subtracting a negative is the same as adding a positive: \[ -10 - (-21) = -10 + 21 \]

2. Now, perform the addition: \[ -10 + 21 = 11 \]

Thus, the result of the expression \(-10 - (-21)\) is \(11\).
