Question

Pls help I have an exam with this

what's 15 - 7 × 2 + 2 ^ 3​

Answer 1

9

Explanation:

Using PEMDAS (Parenthesis, Exponents, Multiply/Divide, Add/Subtract), we will solve the equation step by step.

First, 2^3 is 2*2*2, or 8, giving us a new equation of:
15-7*2+8

Next, 7*2=14, giving us a final equation to solve:
15-14+8

Which solves to 9.
