Understanding Addition

Addition is one of the basic operations of arithmetic. It combines two or more numbers to find their total, which is called the sum. For example, when we add 2, 3, and 5, we get 10, because 2 + 3 + 5 = 10. This calculator helps you quickly find the sum of three numbers. Addition is commutative, meaning the order in which you add numbers doesn't change the sum (e.g., 2+3+5 = 3+5+2). It's also associative, meaning how you group numbers in addition doesn't change the sum (e.g., (2+3)+5 = 2+(3+5)). Addition is used in everyday life, from calculating expenses to measuring ingredients for cooking.
