Cancellation Property for Addition
If a + c = b + c, then a = b
Multiplication Property of -1
a(-1)=-a
Reciprocals of Equals are Equal
If a=b then 1/a=1/b
Definition of Subtraction
a-b=a+(-b)
Definition of Division
a/b = a (1/b), b ≠ 0
A negative number divided by a positive number is a negative number
-x/y = -(x/y)
Property of the Reciprocal of a Product
1/ab = 1/a * 1/b
A negative sign distributes over addition
-(a + b) = -a + -b
The opposite of the opposite of a number, is that number
-(-a) = a
Cancellation Property of Multiplication
if ac=bc then a=b when c is not 0
Multiplication property of zero
a x 0 = 0
Cancellation Property for Division
if a/c = b/c then a = b
Division Distributes over Subtraction
(x - y)/z = x/z - y/z
Division Distributes over Addition
(x + y)/z = x/z + y/z
multiplication property of fractions
xy/ab=x/a*y/b
