Evaluate the following expression

Explanation

Since there are no calculations within parentheses, no exponential expressions, and no multiplication or division, we will perform the additions, working from the left to the right.

This is step 4 of the order of operations rule.

• Use the rule for adding two integers that have different signs: -3 + 5 = 2
  • -3 + 5 + (-12) + 2 = 2 + (-12) + 2
• Use the rule for adding two integers that have different signs: 2 + (-12) = -10
  • = -10 + 2
• Use the rule for adding two integers that have different signs.
  • = -8
