600-(80-25)

To solve this expression, we can follow the order of operations (also known as PEMDAS):

1. Parentheses: Simplify the expression inside the parentheses, which is (80-25): 80 - 25 = 55
2. Subtraction: Subtract the result from step 1 (55) from 600: 600 - 55 = 545

Therefore, the expression 600 - (80-25) equals 545.
