For example:

Let’s take a look at the example above.

We are subtracting because some of the dolphins swim away.

There are **10** dolphins to start with and **5** swim away.

We need to figure out how many are left.

We can do this by subtracting **10 – 5** to get our answer.

10 – 5 = 5

There are **5** dolphins left!

Let’s look at another problem!

Let’s take a look at the example above.

We are subtracting because some of the butterflies fly away.

There are **11** butterflies to start with and **4** fly away.
