1. The problem asks if the expression $1-4(1-4)$ equals 13. 2. First, apply the order of operations: parentheses, then multiplication, then subtraction. 3. Inside the parentheses, calculate $1-4 = -3$. 4. Now the expression is $1 - 4 \times (-3)$. 5. Multiply $4 \times (-3) = -12$. 6. Substitute back: $1 - (-12)$. 7. Subtracting a negative is the same as adding: $1 + 12 = 13$. 8. Therefore, the expression equals 13.
