CSET Math Subtest 1 Latest Version Graded A Multiplicative inverse property value when multiplies by any non zero number =1. reciprocal of value 4/5 X 5/4=1 Algebraic substitution method 2 equations 2 unknowns solve 1 equation with 1 unknown then substitute answer into the other equation. Trichotomy law only three possible relationships between X & Y, X >Y Y >X X =Y Multiplicative property of equality Multiplying/ Dividing the same value to each side of the equation 4X=8 X=2 Zero Product Property Set quadratic equal to zero, factor and solve for each factor. (X-3)(X-4) X-3=0 X-4=0 Additive Property of equality Adding the same number to both sides X+2=10 X+2-2=10-2 Substitution Property Substituting a value for numbers 2(a+b)=3 a+b=9 2(a)=3C Symmetric Property Only Switching sides 10=Y Y=10 Reflexive Property Anything equaling itself 7Y=7Y Multiplicative Identity Multiplied and didn't change anything 5X1=5 Additive Identity The sum of any number and zero is the original number 5+0=0 Distributive Property Multiplying through a parenthesis a(a+b)=ab+ac Associative Property Regrouping a+(b+c)= (a+b)+c Commutative Property Move Around a+b=b+a ab=ba
