(12 X 5 - 2^2) - 5  

PEMDAS (order of operations)

Parentheses, exponents, multiplication/division, addition/subtraction...

We have a set of parentheses and an exponent within it so that is the first operation...

(12 X 5 - 4) -5

Next is multiplication/division

(60-4)-5

Now subtraction in the parentheses

56-5  and the final subtraction

51
