Find the product or quotient.

18-4

Short Answer

Expert verified

The product of the numbers is -72.

Step by step solution

01

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.

02

Step-2 – Example for product of numbers

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

The product of two negative numbers is positive. For example:-7脳-3=21.

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

For example:3-7=-21or7-3=-21.

03

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

18(鈭�4)=鈭�(18鈰�4)=鈭�(72)=鈭�72

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