    We are not allowed to used any type of PEMDAS mnemonic because or department chair doesn’t like the fact that the “P”isn’t accurate–it includes more than parentheses). So, I came up with the acronym GERMDAS, “G”being grouping symbols, which includes parentheses, brackets, braces, absolute value, radicals, and fraction bars. Sometimes, when it seems needed, I have a contest for the students to come up with the best sentence for remembering the acronym; however, since it starts with germ, it’s been fairly easy. :-)
