What is PEMDAS?

YOU may remember learning about PEMDAS in elementary or grade school as a way to remember how to solve an equation.

The acronym often sparks a specific memory of learning how to solve equations, so why it is trending on Twitter in 2021?

What is PEMDAS?

PEMDAS is an acronym that explains the order of operations to do when solving an equation.

Each letter stands for a different operation: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Thus, when solving an equation, you solve the part in parentheses first, then any exponents that appear, then any division portion, and so on.

Also, it is important to remember that multiplication and division rank equally as do addition and subtraction.

Thus, after all parts in parentheses and with exponents are completed, multiplication or division can be done next and the answer will be correct.

One way to also remember the PEMDAS rule is to use the saying "please excuse my dear aunt sally" which creates the same acronym.

Why is PEMDAS trending on Twitter?

PEMDAS began trending on Twitter on July 23, 2021 after one user posted an equation and a poll to find the right answer.

Twitter user "guediouzou" tweeted the equation "2+2×4" and created a poll of four options looking for the right answer.

The four options were: 16, 15, 14, or 13.

Fifty nine percent of those that answered the poll chose 16 as the correct answer.

One user "xclaudius" responded to the poll saying "idek what stresses me out more, the fact that 26% somehow got 13 or the fact that the correct answer isn’t even an option."

Many angry responders have been evoking the acronym and its rules and demanding the answer is 10, which is not even one of the poll options.
