Chapter 0.3, Problem 12E

To determine

The simplified value of the expression $-12\left(15\right)$ .

Answer to Problem 12E

The simplified value of the expression $-12\left(15\right)$ is $-180$ .

Explanation of Solution

Given information:

The expression $-12\left(15\right)$ .

Formula used:

Product of two real numbers is obtained when they are multiplied together. That is two or more numbers are separated by multiplication signs $\left(\right),\times \text{ or }\cdot$ .

Product of a negative integer with a positive integer is always negative.

Calculation:

Consider the expression $-12\left(15\right)$ .

Recall that product of two real numbers is obtained when they are multiplied together. That is two or more numbers are separated by multiplication signs $\left(\right),\times \text{ or }\cdot$ .

Simplify it,

  $\begin{array}{c}-12\left(15\right)=-\left(12\times 15\right)\\ =-180\end{array}$

Thus, the simplified value of the expression $-12\left(15\right)$ is $-180$ .
