Full solution

Q. Compute:\newline−9+(−10) -9+(-10) \newlineAnswer:
  1. Understand operation: Understand the operation. We need to add −9-9 and −10-10, which are both negative numbers.
  2. Predict sign of sum: Predict the sign of the sum. Since both numbers are negative, the sum will also be negative.
  3. Perform addition: Perform the addition. Add the absolute values of the numbers: 9+10=199 + 10 = 19.
  4. Apply predicted sign: Apply the predicted sign to the sum. The sum of two negative numbers is negative, so the result is −19-19.
  5. Verify result: Verify the result. Adding two negative numbers should result in a larger negative number, which is consistent with our result.
