Questions: Evaluate the following. -5 times (-9)= square 10 div (-5)= square

Transcript text: Evaluate the following. \[ \begin{array}{l} -5 \times(-9)=\square \\ 10 \div(-5)=\square \end{array} \]

Solution

Solution Steps

To solve these problems, we need to apply basic arithmetic operations with integers. For multiplication, remember that the product of two negative numbers is positive. For division, dividing a positive number by a negative number results in a negative quotient.

Step 1: Evaluate the Multiplication

We need to evaluate the expression \( -5 \times (-9) \). Since the product of two negative numbers is positive, we have: \[ -5 \times (-9) = 45 \]

Step 2: Evaluate the Division

Next, we evaluate the expression \( 10 \div (-5) \). Dividing a positive number by a negative number results in a negative quotient: \[ 10 \div (-5) = -2.0 \]
