Addition is a fundamental arithmetic operation that combines two or more numbers to find their total sum. It's one of the four basic operations in mathematics, along with subtraction, multiplication, and division.
To add multiple numbers, simply combine them using the addition operation (+). Start from left to right: add the first two numbers, then add the third to that result, and continue until all numbers are added.
