Capitolo 1, Problema 35
Find each product or quotient where possible. See Example 2. -8(-5)
Guida verificata passo dopo passo1
Identify the operation involved in the expression. Here, the expression is a product of two numbers: \(-8\) and \(-5\).
Recall the rule for multiplying integers: the product of two negative numbers is positive.
Set up the multiplication as \((-8) \times (-5)\).
Multiply the absolute values of the numbers: \(8 \times 5\).
Apply the sign rule to determine the final sign of the product, which will be positive since both factors are negative.
