How do you add two or more numbers

Response:
You can add numbers by treating each number as a count of items and then counting all of the items to get a total result which is the sum of the numbers.  

The process of adding numbers is known as addition and is one of four basic maths operations.  This area of maths is known as arithmetic.

Counting the quantity of items is the same as repeatedly adding 1.

For example, adding the numbers two and three (or 2 + 3)  is the same as adding one (1) two times and then adding one (1) three times.
