Given the equation:
7 + (5 – 9)2 + 3(16 ÷ 8)
Solution:
We can solve the given equation by using PEMDAS, which stands for Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction.
Since we do not have any exponent, we simply start first with the parenthesis, multiplication, and addition.
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 - 8 + 6
= 5
Final answer:
5
