Okay. I get my order of operations mixed up over and over again..which is proably the reason I miss so many of my problems.
Problem one is:
14-16\8+9*5=
I did:
14-2+9*5
12+9
21*5=
105
Problem two is:
10-3(5-2)=
I did:
7*3=
21

The order of operations:
First: do all exponents.
Second: do all multiplication and/or divisions.
Third: do all additions and/or subtractions.
In your case: 14-16/8+9*5=
There are no exponents!
Thus do the second: 14−2+45.
Then do the third: 57.
