Well, use PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
8+6^2/11+7*2
I don't see any parenthesis.
8+6^2/11+7*2
I see exponents.
6^2=6*6=36
Rewrite the problem.
8+36/11+7*2
Next up is multiplication.
7*2=14
Rewrite it.
8+36/11+14
Division.
36/11=3.27 (repeating)
So round it to 3.28
Rewrite it.
8+3.28+14
Then just add
8+3.28+14=25.28
Hope this helps :)
