Step-by-step explanation:
PEMDAS (parenthesis, exponents, multiplication / division, addition /subtraction.) I will use these as abbreviations.
8^2 + 9 (12/3*2) - 7
P: Start with P, and inside P go left to right with M/D
D: 8^2 + 9 (4*2) - 7
M: 8^2 + 9 (8) - 7
E: The next step is E, so I will do 8^2
64 + 9 (8) - 7
M/D: I will then multiply from left to right
64 + 72 - 7
A/S: Finall I will add and subtract from left to right.
A: 136 - 7
S: 129
