Question

evaluate the expression when w = -3. w - 10

Explanation:

Step1: Substitute \( w = -3 \) into the expression

We have the expression \( w - 10 \). Substitute \( w = -3 \) into it, so we get \( -3 - 10 \).

Step2: Calculate the result

To calculate \( -3 - 10 \), we know that subtracting a number is the same as adding its opposite. So \( -3 - 10 = -3 + (-10) \). When adding two negative numbers, we add their absolute values and keep the negative sign. The absolute value of \( -3 \) is \( 3 \), and the absolute value of \( -10 \) is \( 10 \). So \( 3 + 10 = 13 \), and then we keep the negative sign, so the result is \( -13 \).

Answer:

\( -13 \)
