Question

Use a number line to find the sum. $$-10+4$$

Short answer

The sum of -10 and 4 is -6

Step-by-step solution

Draw the number line

First, draw a number line. Mark the numbers -10 to 10 on it.

Find starting point

Since the first number in the sum is -10, place a point or marker at -10 on the number line. This will be the starting point.

Add the second number

The problem asks to add 4 to -10. From the starting point at -10, move 4 units to the right because adding a positive number means moving to the right on the number line.

Determine the result

The point will end up on -6, which is the sum of -10 and 4.
