12918755, My guess is because all the work comes from remembering the order Posted by Mafamaticks, Thu Oct-29-15 11:28 AM
If you're starting to do PEMDAS then you already know how to multiply, divide, add, subtract, and figure out exponents. You just need to remember which order to do the equations in.
And if you recite the acronym, you halfway memorized the order already.
