What is addition??

Answer if u want​

Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.

Addition is when you count up to see how many of something or somethings you have so say I have 2 apples and 6 oranges and I wanted to find out how many I have I would write it like

6 + 2 or 2 + 6 and I would add it up to find out I have 8 fruit in total hope that helps!
