Question

evaluate -5 - 6×(-9).

Explanation:

Step1: Perform multiplication

First, calculate \( 6 \times (-9) \). Remember that a positive times a negative is negative, so \( 6 \times (-9) = -54 \). But in the expression, it's \( -6 \times (-9) \). A negative times a negative is positive, so \( -6 \times (-9) = 54 \).

Step2: Perform subtraction (or addition)

Now, substitute back into the original expression: \( -5 + 54 \) (because subtracting a negative is like adding the positive). Then, \( -5 + 54 = 49 \).

Answer:

\( 49 \)
