Addition

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 Numbers it is:      1 + 1 = 2
     
And in words it is:   "One plus one equals two"

Example: If you add 2 and 3 you get 5. You would write it like this:
2 + 3 = 5

Try It

Write this down, with the answer, using numbers:
4+3=?
You should get:   4 + 3 = 7  

Swapping Places

Swapping the position of the numbers you are adding still gets the same result!
3 + 2 = 5 3+2=5
... also ...  
2 + 3 = 5 2+3=5

More Examples:
5 + 1 = 1 + 5 = 6
7 + 11 = 11 + 7 = 18
4 + 100 = 100 + 4 = 104
