# Subtracting Integers on a Number Line

With the help of number line we can subtract integers.

It is better to show on examples how to do this.

**Example 1**. Find -1-4.

We draw -1 on a number line. Since we subtract positive number (4) we move 4 units to the left. Result is -5. So, -1-4=-5.

**Answer: -5**.

Let's see how to subtract negative numbers.

**Example 2**. Find -1-(-6).

We draw -1 on a number line. Since we subtract negative number (-6) we move 6 units to the right. Result is 5. So, -1-(-6)=5.

**Answer: 5**.

Now, do the following exercise to remember this topic better.

**Exercise 1**. Find 4-8.

**Answer: -4**.

Next exercise.

**Exercise 2**. Find 1-(-1).

**Answer: 2**.
