Properties of Real Numbers

Try your hand at these activities to practice the algebraic properties we discussed in class. You must complete three activities by the next class.

AB
COMMUTATIVE PROPERTY3 + 8 = 8 + 3
ASSOCIATIVE PROPERTY2 + (5 + 9) = (2 + 5) + 9
DISTRIBUTIVE PROPERTY5(x + 6) = (5 * x) + (5 * 6)
ADDITIVE IDENTITY4 + 0 = 4
MULTIPLICATIVE IDENTITY7 * 1 = 7
ADDITIVE INVERSE3 + (-3) = 0
MULTIPLICATIVE INVERSE2 * 1/2= 1
ADITIVE PROPERTY OF EQUALITYIf 2+5 =7, then 2+5+7 = 7+7
SUBTRACTION PROPERTY OF EQUALITYIf 4+8=12, then 4+8-3=12-3
MULTIPLICATION PROPERTY OF EQUALITYIf 2*3=6, then 2*3*5=6*5
DIVISION PROPERTY OF EQUALITYIf 6*4=24, then (6*4)/2=24/2
CLOSUREWhen you combine any two elements of a set, the result is also included in that set.
TRICHOTOMY PROPERTYWhen any two numbers, a and b, are compared, a<b, a=b, or a>b.
