Question

Find each sum or difference.

$-8+13$

Step-by-Step Solution

Answer

The sum of numbers is 5.

Step 1. Plot – 8 on a number line.

Step 2. Determine side to go.

After – 8 we have +13, which means we have to go 13 units to the right.

Step 3. On graph move 13 units to the right.

Step 4. Interpret the graph.

On the graph, we see that 13 units right from -8 are 5.
This means – 8 + 13 = 5.
