Question

Find each sum or difference.

$-77+\left(-46\right)$

Step-by-Step Solution

Answer

The sum of numbers is –123.

Step 1. Determine to add or subtract.

Since - 77 and – 46 both are of the same signs. So we will add them.

Step 2. Determine the sign.

Add the absolute values. And the result will take the common sign, that is negative. 

$-77+(-46)=-\left(\right|-77|+|-46\left|\right)$ 

Step 3. Simplify.

We know that the absolute values of the non-zero numbers are always positive.

So, $-\left(\right|-77|+|-46\left|\right)=-(77+46)=-123$
