# How do I multiply two-digit numbers more easily?

## How can you multiply by two-digit numbers?

Can you multiply by **two-digit** numbers like **14** or **37**?

It looks a bit difficult, doesn't it? It can be easier if you **partition** the number into two parts. Instead of multiplying by **29** you can multiply by **20** and then multiply by **9** separately and then add the answers together.

Instead of multiplying by **34** you can multiply by **30** and then multiply by **4** separately and then add the answers together.

### Example

**3 x 34 = ?**

Split the **34** into **30** and **4**.

**3 x 30 = 90**

**3 x 4 = 12**

Then add these together

**90 + 12 = 102**

Another strategy is to multiply by a near number that is easier to work with and then add or take away the difference.

### Example

**6 x 29 = ?**

It might be easier to do this as **6 x 30 = 180**

Then you need to take away **6 x 1** (because **29** is **30 - 1**)

**6 x 1 = 6**

**180 - 6 = 172**

Was that easier? Why not try these strategies again next time you have to multiply by two-digit numbers.
