Question

add:
8 + -9 =
submit

Explanation:

Step1: Understand the operation

We need to add a positive number (8) and a negative number (-9). This is equivalent to subtracting the absolute value of the negative number from the positive number when the absolute value of the negative number is larger.

Step2: Perform the calculation

$8 + (-9) = 8 - 9$ (because adding a negative is the same as subtracting the positive). Then, $8 - 9 = -1$.

Answer:

-1
