To determine

To Rewrite: The expression $-5-13$ as sum of integers.

Answer to Problem 1QC

The expression is $-5+\left(-13\right)$.

Explanation of Solution

Given information:

The expression is $-5-13$ .

Formula used:

Subtraction is a process of addition of additive inverse of second number.

Additive inverse of $a$ is $-a.$

Calculation:

Consider the expression $-5-13$ .

Recall that the Subtraction is a process of addition of additive inverse of second number.

Additive inverse of $a$ is $-a.$

Observer that additive inverse of $13$ is $-13$ .

Use it,

  $-5-13=-5+\left(-13\right)$

Thus, the expression can be rewrite as $-5+\left(-13\right)$ .
