### In this lesson:

Adding and subtracting 2-figure numbers that don’t involve any carry figures

## Adding 2-Figure Numbers

Suppose you want *22 + 34*.

You can imagine the numbers one below the other if you like:

22

+ 34

——

56

You can see that the **tens total** is 5 and the **units total** is 6, which gives 56.

This is easy because there are no carries.

## Alternative Method

Another way to add 22 + 34 is to start with the bigger number, 34, and add 20. This makes 54.

Then add the 2 to make 56.

## Subtraction

Subtractions too can be very easy.

For example 57 – 33 = 24.

Just subtract the tens and then subtract the units.

Imagine it like this if you like:

57

– 33

——

24

## Key Points of this Lesson:

- For addition, just add the tens first, then add the units
- For subtraction, just subtract the tens and then the units
