Subtracting One-Digit Numbers from Two-Digit Without Regrouping

Your sister bought18 cupcakesfor your birthday party. Your friendsate 6during your party. How many cupcakes wereleft?

How can we figure this out? 🤔

We subtract!

In the past, you drew pictures or counted down. That’s going to be harder to do with two-digit numbers.

When we subtract with two-digit numbers, we **stack them** on top of each other.

Make sure to line up the the **Ones **digit numbers on the right (👉)! ✅

🤓This is called writing an equation in **column form.**

When we subtract with two-digit numbers, we subtract the numbers in the **Ones column first**.

This means we subtract:

8 - 6 = ____

Now, we can count down!

8 - 6 = 2

Good job! 🤗 Now you can put 2 in the Ones column.

Great job! 💪 Now, we need to subtract the Tens column.

There’s nothing in the second number, so we just bring down the top number!

That’s it! We got 12.

You have 12 cupcakes left!

Let’s try another one.

26 - 3 = ______

First, let’s **stack them** on top of each other.

Remember the **bigger number goes on top**!

Now, let’s subtract the Ones column.

Great! Now, we can bring down the 2 in the Tens column.

You’ve got it! 🤗 Great job!

Now, you can practice what you've just learned!
