AEM = Adding Exponents which should be Multiplied CES = Cancelling Everything in Sight CNFE = Confusing Negative and Fractional Exponents ECF = Error Carried Forward (without additional penalty) EPE = Equation Properties for Expressions FP = Frivolous Parentheses GOWU = Goal Of Work is Unclear LFB = Linear Function Behavior MEA = Multiplying Exponents which should be Added MIP = Multiplication Ignoring Powers MND = Multiplication Not Distributive MRRZ = Misunderstood Relationship between Roots and Zeros MT = Empty MWP = Multiplication without Parentheses OO = Order of (Algebraic) Operations PUML = Poor Use of Mathematical Language UAS = Undo Addition with Subtraction UEC = Using Equals as a Conjunction UMD = Undo Multiplication with Division
