Algebraic Expressions and PEMDAS

Order of Operations is Important

Whether you’re new to algebraic expressions or working on complicated equations, remembering the order of operations is crucial to getting the correct answer.

The order of operations is frequently referred to as PEMDAS. “Please Excuse My Dear Aunt Sally” is the longer version of this mnemonic. Both try to remind the user to follow the order of operations:

Parenthesis: First do the arithmetic in the parentheses. This is not only the correct first step, but helps simplify what could look like a long problem.

Exponents: Next up is exponents. By getting these out of the way, you’ve simplified the equation even further. The rest is easy!

Multiplication

Division

Addition

Subtraction

    When we used “Brackets” instead of “Parenthesis”, “Of” io “Exponent”, the mnemonic BODMAS was much easier to remember than looking for excuses for your aunt Sally. However I like your new language.
