Multiplication is repeated addition.

How to Multiply by 4

When you multiply a number by 4, it’s like adding equal groups four times.

For example:

4 x 4 = ?

4 × 4 is a shortcut for writing:

4 + 4 + 4 + 4 = ?

Let’s draw 4 groups, with 4 stars in each group.

If we count the stars altogether, we’ll have 16 stars.

So we see that 4 x 4 is 16!

Secret Trick: Skip count!

Do you know what 8 x 4 is?

If you don’t, just skip count by one of the numbers to find out. Then memorize it!

We can skip count by either factor. Let’s skip count by 8, four times:

8, 16, 24, 32

So 8 x 4 = 32! 

You can use skip counting to solve any multiplication problem you don’t know, but then it’s important to memorize the answers.

Learn with an example

Multiply.

4 × 1 =

The identity property of multiplication says that the product of any number and 1 is that number. So, the product of 4 and 1 is 4.

4 × 1 = 4

You can also look at this model to see that 4 × 1 = 4. This model shows 4 rows with 1 dot in each row. There are 4 dots in all.

This number line also shows that 4 × 1 = 4. Count by 1s on the number line. Count forward 4 times.

The arrow ends at 4.

4 × 1 = 4

Multiply.

4 x 0 =

The zero property of multiplication says that the product of any number and 0 is 0. This means that 0 times any number is 0.

So, the product of 4 and 0 is 0.

4 x 0 =0

Multiply.

2 × 4 =

This array shows that 2 × 4 = 8. It has 2 rows with 4 dots in each row.

There are 8 dots in all.

2 × 4 = 8

This number line also shows that 2 × 4 = 8. Count by 4s on the number line. Count forward 2 times.

The last arrow ends at 8.

2 × 4 = 8
