AEM = Adding Exponents which should be Multiplied CADD = Confusing AntiDerivative and Derivative CES = Cancelling Everything in Sight CFE = Check For Extremum (i.e., not all critical nos. correspond to extrema) CNFE = Confusing Negative and Fractional Exponents ECF = Error Carried Forward (without additional penalty) EPE = Equation Properties for Expressions FPR = False Product Rule 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 NAD = Not an AntiDerivative of the integrand NAE = The quantities you have separated with an equals sign are Not Actually Equal OO = Order of (Algebraic) Operations PUML = Poor Use of Mathematical Language RFPRF = Reverse False Product Rule is False UAS = Undo Addition with Subtraction UEC = Using Equals as a Conjunction UMD = Undo Multiplication with Division UPR = Use the Product Rule UQR = Use the Quotient Rule WLINV = Wrong Limits of Integration in the New Variable
