Chapter 0.4, Problem 28E

To determine

To calculate: The simplified form of $-38.9+24.2$ .

Answer to Problem 28E

The simplified form of $-38.9+24.2$ is $-14.7$ .

Explanation of Solution

Given information:

The statement “ $-38.9+24.2$ .”

Formula used:

When one positive and one negative numbers are added then the absolutedifference between the two is taken and sign of greater number is put in front of it.

Consider the provided statement “ $-38.9+24.2$ .”

Recall that when one positive and one negative numbers are added then the absolute difference between the two is taken and sign of greater number is put in front of it.

So, the given expression can be simplified as,

  $\begin{array}{c}-38.9+24.2=-\left(38.9-24.2\right)\\ -38.9+24.2=-14.7\end{array}$

Hence, the simplified form of $-38.9+24.2$ is $-14.7$ .
