Chapter 0.4, Problem 32E

To determine

To calculate: The simplified form of $43.2+\left(-27.9\right)$ .

Answer to Problem 32E

The simplified form of $43.2+\left(-27.9\right)$ is $15.3$ .

Explanation of Solution

Given information:

The statement “ $43.2+\left(-27.9\right)$ .”

Formula used:

When two numbers are added or subtracted then their absolute value is taken first and sign of greater number is put in front of it.

Consider the provided statement “ $43.2+\left(-27.9\right)$ .”

Recall that when two numbers are added or subtracted then their absolute value is taken first and sign of greater number is put in front of it.

So, the given expression can be simplified as,

  $\begin{array}{c}43.2+\left(-27.9\right)=43.2-27.9\\ 43.2+\left(-27.9\right)=15.3\end{array}$

Hence, the simplified form of $43.2+\left(-27.9\right)$ is $15.3$ .
