Question

Find each sum or difference.

$11+\left(-19\right)$

Step-by-Step Solution

Answer

The sum of numbers is –8.

Step 1. Plot 11 on a number line.

Step 2. Determine side to go.

After 11 we have –19, which means we have to go 19 units to the left. 

Step 3. On graph move 19 units to the left.

Step 4. Interpret the graph.

On the graph, we see that 19 units left from 11 is –8.
This means 11 + (–19) = – 8.
