Answer 13

\[3^2+(8-2) \cdot 4-\frac{6}{3} \\ 3^2+( 6 ) \cdot 4 -\frac{6}{3}\]
We performed any operations inside grouping symbols first.

------------
Now we want to look at exponents.
Do you see any exponents?

Answer 14

yes

Answer 15

So we must evaluate the part with exponent
3^2=?
remember 3^2 means 3*3
not 3*2

Answer 16

\[3^2+(8-2) \cdot 4-\frac{6}{3} \\ 3^2+( 6 ) \cdot 4 -\frac{6}{3} \\ 9+(6) \cdot 4-\frac{6}{3}\]
Second step way take care of the exponents.

-----
Third, we want to perform multiplication/division as it occurs from left to right
so 6(4)=? and 6/3=?


---
Then last perform addtion/subtraction as it occurs left to right

See if you can finish up and I will check your answer.
