PEMDAS- Please excuse my dear Aunt Sally
The informant was introduced to this mnemonic device in late elementary school and middle school as a method to learn the order of operation: parentheses, exponents, multiplication, division, addition, and subtraction. When solving a mathematical equation, the order that one performs the operations is important to reach the final answer. The students were taught “Please excuse my dear Aunt Sally”; however, the informant and many other students in the class would change to simply say “Pemdas”, a made-up word, but one they could still remember. The phrase was less appealing to the informant and their peers as it was long and required them to break down the phrase into the first letters of each word to get the actual desired content.
The students were taught the phrase “Please excuse my dear Aunt Sally” by their teachers, but instead made their own mnemonic device to better match their preferences. The shorter device may point to a desire for efficiency in those who use it as they prefer a more straight-forward learning method than one that might be seen as ‘creative’.
