Addition is fun!

Addition is ...

... bringing two or more numbers (or things) together to make a new total.

Here 1 ball is added to 1 ball to make 2 balls:
Using Numerals it is:		1 + 1 = 2
And in words it is:		"One plus one equals two"

Example: When we add 2 and 3 we get 5.

We can write it like this:

2 + 3 = 5

Swapping the position of the numbers we are adding still gets the same result!

3 + 2 = 5
... also ...
2 + 3 = 5

More Examples:

5 + 1 = 1 + 5 = 6

7 + 11 = 11 + 7 = 18

4 + 100 = 100 + 4 = 104

Larger Numbers: Use Addition in Columns

To add larger numbers use Column Addition :

Names

Other names for Addition are Sum, Plus, Increase, Total

And the numbers to be added together are called the "Addends":
