Chapter 0, Problem 8PRT

To determine

The simplified value of the expression $-5.6+\left(-30.7\right)$ .

Answer to Problem 8PRT

The simplified value of the expression $-5.6+\left(-30.7\right)$ is $-36.3$ .

Explanation of Solution

Given information:

The expression $-5.6+\left(-30.7\right)$ .

Formula used:

Addition of two real numbers is obtained when they are added together. That is two or more numbers are separated by addition sign $+$ .

Addition of a negative real number with a negative real number is always negative.

Calculation:

Consider the expression $-5.6+\left(-30.7\right)$ .

Recall that addition of a negative real number with a negative real number is always negative. Then,

Apply it,

  $-5.6+\left(-30.7\right)=-\left(5.6+30.7\right)$

Again recall that addition of two real numbers is obtained when they are added together. That is two or more numbers are separated by addition sign $+$ .Then,

Simplify it,

  $-\left(5.6+30.7\right)=-36.3$

Thus, the simplified value of the expression $-5.6+\left(-30.7\right)$ is $-36.3$ .
