However, multiplication and division MUST come before addition and subtraction. The acronym PEMDAS is often used to remember this order.

Which is the correct order of mathematical operators?

We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How do you introduce the order of operations?

If your students have already studied exponents, you can teach the acronym PEMDAS which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. The phrase “Please Excuse My Dear Aunt Sally” will help them remember the order of those letters.

#### In what order do you solve equations?

The order of operations is Parenthesis, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This can be remembered in two ways: “Please Excuse My Dear Aunt Sally” or PEMDAS.

What comes first multiply or add first?

Due to PEMDAS, or the order of operations, you should multiply the numbers first. For instance, if given the equation 3+2*4, you should multiply 2*4 before adding 3 to the result (giving you an answer of 11) You should multiply first unless brackets are present.

Do you add or subtract before or after multiplication?
