Any quantity is equal to itself.
For any number a, a=a.
5=5 or 4+7 = 4+7
If one quantity equals a second quantity, then the second quantity equals the first.
For and numbers a and b, if a=b then b=a.
If one quantity equals a second quantity and the second quantity equals a third quantity, then the first quantity equals the third quantity.
For any numbers a,b, and c, if a=b and b=c, then c=a
If 6+9 = 3+12 and 3+12 = 15, then 6+9 = 15
A quantity may be substituted for its equal in any expression.
If a=b, then a may be replaces by b in any expression.
If n = 11 then 4n = 4x11
For any number a, the sum of a and 0 is a.
a + 0 = 0 + a =a
2 + 0 = 2 or 0 + 2 = 2
A number and its opposite are additive inverses of each other.
a +(-a) = 0
3 + (-3) = 0 or 4-4 = 0
For any number a, the product of a and 1 is a.
Multiplicative Property of Zero
For any number a, the product of a and 0 is 0.
For every number a/b, where a, b does not equal 0, there is exactly one number b/a such that the product of a/b and b/a is 1.
a/b x b/a=1 b/a x a/b=1
4/5 x 5/4=20/20 or 1
5/4 x 4/5=20/20 or 1
Communtative Property of Addition
The order in which you add numbers does not change their sum.
For any numbers a and b, a+b=b+a
Commutative Property of Multiplication
The order in which you multiply numbers does not change their product.
For any numbers a and b,
a x b=b x a
7 x 11=11 X 7
Associative Property of Addition
The way you group three or more numbers when adding does not change their sum.
For any numbers a, b and c,
Associative Property of Multiplication
The way you group three or more numbers when multiplying does not change their product.
For any numbers, a, b and c,
(2 x 6) x 9=2 x (6 x 9)
