Let's learn about addition

Slide 1 - Slide

What Does Addition Mean?
Addition means to add two or more numbers together to make one number that is greater in value. This number is called the sum.  
When we want to add numbers together, we use the plus sign:

+

Slide 2 - Slide

What does the (=) sign mean?
This sign is called the equal sign! This is the symbol that comes before the answer to the problem! So the symbol (=) will appear before the sum in an addition problem, and before the difference in a subtraction problem.
