| When we add two small numbers together, | ||
| we can think of it as putting two small groups of stuff together: | ||
|
|
||
|
Put 5 together with 4 and you get 9 |
||
| When we put two numbers together, it's called adding. | ||
| In math talk we use numbers and this: | ||
|
+ |
||
|
It's called a "plus" sign. |
||
| Example: | ||
|
5 + 4 |
||
| To say what we get, we use this: | ||
|
= |
||
|
It's called an "equal" sign. |
||
| Example: | ||
|
5 + 4 = 9 |
||
| More Examples: | ||
|
|
||
|
3 + 6 = 9 |
||
|
|
||
|
2 + 8 = 10 |
||
| There are a couple of ways to write this stuff. | ||
| Sometimes we write: | ||
|
2 + 8 = 10 |
||
| But most of the time we write: | ||
|
|
||
| The way adding works, it doesn't matter which number you write first. | ||
| You get the same answer either way: | ||
