Related Addition Equations

Let's review addition equations.

The numbers that you combine together are called **addends**.

Addends come before and after the (+) sign.

The number after the equal sign is called the **sum**.

If you** swap the addends**, the sum does not change.

So, if **1+ 6 = 7**, then **6 + 1 = 7.**

These kinds of equations are like a family. They have the same numbers but are arranged differently.Ā

They are known as **related equations.**

**Related addition equations **share the same addends but in a different order. They also have the same sum.

š¤ If you have an addition problem, how can you find a related equation?

š Just switch the addends around.

So what's the related addition equation to **2 + 8 = 10?**

Yes! It's **8 + 2 = 10.**

Congratulations. You now understand **related addition equations.** Start your practice below.
