**Things to remember:**

- If we multiply by 1 the number stays the same!
- If we multiply by 0 the answer is always 0!

Multiplying numbers can be simple when we have **1**s or **0**s. If we multiply by 1 the number doesn’t change, if we multiply by 0 the answer is always 0.

What is 12\times0\times4?

12\times0\times5=0\times4=0

** **

**TIP: **Whenever there is a multiplication with a 0, the answer will always be **0**!

What is 315\times217\times0?

Try multiplying the 0 first.

315\times217\times0=315\times0=0

When we multiply by 1, our numbers stay the same!

What is [/latex]5\times1\times8[/latex]?

5\times1\times8=5\times8=40

Let’s look at some more examples:

1\times4\times8=4\times8=32

3\times1\times3=3\times3=9

5\times4\times1=5\times4=20

**TIP: **When there is a \times1, we can just ignore it!

You might also be asked a question like “What is the answer to [/latex]6\times6\times5[/latex]?” So we’ll have two multiplications to do. But you can decide on which order is easiest for you.

6\times6\times5=36\times5=180

6\times6\times5=6\times30=180

**Question 1:** What is 6\times0\times8?

## Example Questions

**Question 1:** What is 6\times0\times8?

There is a 0, so the answer has to be 0! But let’s just check

6\times0\times8=0\times8=0

6\times0\times8=0

**Question 2:** What is 9\times1\times4?

One of the multiplications is a 1, so we can start by ignoring it.

9\times1\times4=9\times4=36

9\times1\times4=36
