Follow order of operations:

6-1*0+2/2. First thing we do is multiply.

6-0+2/2. Second, we divide.

6-0+1. Lastly, we add all the terms together, neglecting the -0 because that doesn't represent any change.

6+1 = 7 (Answer)

The easiest way is to memorize PEMDAS.   
 
Parenthesis
Exponents
Multiply
Divide
Add
Subtract
 
Using this we get 
 
6-1*0+2/2
6-0+2/2 (Multiply)
6-0+1 (Divide)
=7 (add and subtract)

Order of (math) operations says do in this order:  parentheses, multiply, divide, add, subtract.

So 6 - 1 x 0 + 2 / 2 = 6 - 0 + 1  (1x0 = 0, and 2/2 = 1) = 7
