13 – 2 (1 – 15) ÷4 Simplify
To simplify the expression, we need to follow the order of operations (also known as PEMDAS).
First, we simplify the expression inside the parentheses: (1 - 15) = -14.
Next, we perform the division: (-14) ÷ 4 = -3.5.
Finally, we calculate the subtraction and multiplication from left to right: 13 - 2 = 11, and 11 x (-3.5) = -38.5.
Therefore, the simplified expression is -38.5.
