What are the basic operations?
Basic Operations. The basic arithmetic operations for real numbers are addition, subtraction, multiplication, and division.
What is addition and subtraction called?
Addition and subtraction are two of the ways we work with numbers. We call them arithmetical operations. The word operation comes from the Latin ‘operari’, meaning to work or toil. Of the four arithmetical operations on numbers, addition is the most natural. Subtraction and addition are inverse operations.

Why is there an order of operations?
The order of operations is a rule that tells you the right order in which to solve different parts of a math problem. Subtraction, multiplication, and division are all examples of operations.) The order of operations is important because it guarantees that people can all read and solve a problem in the same way.
What comes first division or subtraction?
Order of operations tells you to perform division before subtraction. Then subtract. Simplify 60 – 30 ÷ 3 • 5 + 7. Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction.

Which is performed first, between multiplication and division, is determined by which comes first when reading from left to right. The same is true of addition and subtraction. Don’t let the saying confuse you about this!
Which is the most basic addition and subtraction?
