8-1(8-1)

To solve the expression \( 8 - 1(8 - 1) \), we follow the order of operations (parentheses, exponents, multiplication and division (from left to right), addition and subtraction (from left to right)).

1. First, solve the expression inside the parentheses: \[ 8 - 1 = 7 \]

2. Next, replace the parentheses in the original expression: \[ 8 - 1(7) \]

3. Now, multiply: \[ 1 \times 7 = 7 \]

4. Finally, subtract: \[ 8 - 7 = 1 \]

So, the final result is \( 1 \).
