Given the numerical equation:
-5 + 2 - 7 - (-12)
Solution:
In order to determine the answer to the numerical equation, we apply the rule of PEMDAS, which generally stands for Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction. We must also take note that when multiplying or dividing signs with similar sign the answer will be positive, hence if the signs are opposite, the answer will become negative.
= -5 + 2 - 7 - (-12)
= -5 + 2 - 7 + 12
= -10 + 12
= 2
Final answer:
= 2
