Practice with the properties of actual numbers. Words NUMBERS implies the answer will certainly deal only with numbers. Words X suggests the answer will contain a variable, yet not necessarily the variable x.

Distributive residential property (Numbers)
AB
3(5 + 2) = 15 + 6
Commutative residential or commercial property of enhancement (Numbers)3 + 7 = 7 + 3
Commutative building of Multiplication (Numbers)2 • 10 = 10 • 2
Associative residential or commercial property of addition (Numbers)5 + (6 + 7) = (5 + 6) + 7
Associative property of Multiplication (Numbers)6 • (3 • 2) = (6 • 3) • 2
Additive identification (Numbers)6 + 0 = 6
Additive inverse (Numbers)5 + (-5) = 0
Multiplicative identification (Numbers)5 • 1 = 5
Multiplicative station (Numbers)8 • (1/8) = 1
Reflexive residential property (x)x + 4 = x + 4
Distributive home (x)x • (4 + 6) = 4•x + 6•x
Commutative residential property of addition (x)(x + 6) + 5 = (6 + x) + 5
Commutative residential or commercial property of Multiplication (x)(5a) • b = b • (5a)
Associative property of enhancement (x)(x + y) + 3 = x + (y + 3)
Associative residential or commercial property of Multiplication (x)(6x) • y = 6 • (xy)
Additive identification (x)x + 0 = x
Additive inverse (x)b + (-b) = 0
Multiplicative identification (x)x • 1 = x
Multiplicative inverse (x)x • (1/x) = 1
Reflexive residential or commercial property (Numbers)2 = 2
Symmetric property (Numbers)If 2 + 6 = 8, climate 8 = 2 + 6
Symmetric residential or commercial property (x)If b = 3, then 3 = b
Transitive building for x and also bIf x = b and also b = 3, then x = 3
Transitive residential or commercial property for a and cIf a = b + 4 and b + 4 = c, climate a = c
Substitution residential property (Numbers)(5 + 3) • 2 = 8•2
Substitution home (x)(7 - 4) • x = 3x
Multiplicative building of Zero (Numbers)9 • 0 = 0
Multiplicative property of Zero (x)a • 0 = 0
