Short Answer

Expert verified

The product of the numbers is $- 72$ .

Step by step solution

Step-1 – Apply the concept of product

The product of two similar sign numbers is always positive.

The product of two numbers with different signs is always negative.

Step-2 – Example for product of numbers

The product of two positive numbers is positive as well. For example: $7 \times 3 = 21$ .

The product of two negative numbers is positive. For example: $(- 7) \times (- 3) = 21$ .

And the product of two numbers with different signs is negative.

For example: $3 (- 7) = - 21 or 7 (- 3) = - 21$ .

Step-3 – Evaluate the product

To evaluate the product $18 (- 4)$ ,observe that the sign of both numbers is different. So, the product will be negative

$\begin{matrix} 18 (- 4) = - (18 \cdot 4) \\ = - (72) \\ = - 72 \end{matrix}$

Thus, the product of the given numbers is $- 72$ .
