Commutative Property Order changes but the total stays the same. (Example: a + b = b + a)
Associative Property Grouping changes using parentheses but the order stays the same. (Example: (a+b)+c = a+(b+c))
Identity Property Adding 0 or multiplying by 1 keeps the number exactly the same. (Example: x + 0 = x)
Inverse Property Using opposites or flipped fractions to cancel a number down to 0 or 1. (Example: 5 + -5 = 0)
Property of Zero Multiplying any algebraic term by 0 results in exactly 0. (Example: 7x * 0 = 0)
Distributive Property ,Multiplying an outside factor across everything inside the parentheses. (Example: 3(x + 4) = 3x + 12)
Minus Sign Rule ,Always glue a minus sign to the term directly to its right. Treat it as a negative.
Double Negative Rule A negative number multiplied by a negative number ALWAYS flips to a positive.
Negative x Positive A negative number multiplied by a positive number ALWAYS results in a negative.
-3(2x - 5) Simplified -6x + 15 (Because -3 times 2x is -6x and -3 times -5 flips to +15)
