Method used:
Adding two integers with the unlike sign:
Step 1: Subtract the lesser absolute value from the greater absolute value.
Step 2: Use the sign of the number with the greater absolute value as the sign of the sum.
Calculation:
The given expression is 12 + (-7).
Step 1: Find the absolute values.
|12| = 12 and |-7| =7.
Subtract 12 — 7 to get 5.
Step 2: Here 12 has the greater absolute value and is positive, so the sum is also positive.
That is, 12 + (-7) =5.
Therefore, the sum of the expression 12 + (—7) is 5.
