The inverse property states that for a non-zero number x, there is a number y such thatx*y = y*x = 1, where 1 is the multiplicative identity.y is written as x-1 or 1/x.
The nine most common properties are:Associative property of addition (a +b) + c = a + (b+c)Commutative property of addition a + b = b + aAdditive identity property of 0 a + 0 = 0 + a = aExistence of additive inverses For every a there exists -a so that a + (-a) = (-a) + a = 0Associative property of multiplication (a x b) x c = a x (b x c)Commutative property of multiplication a x b = b x aMultiplicative identity property 1 a x 1 = 1 x a = aExistence of multiplicative inverses For every a ≠0 there exists 1/a so that a x 1/a = 1/a x a = 1Distributive property of multiplication over additions a x (b + c) = a x b + a x c

the op-op property stands for the opposite of opposites property. the rule tells you: an odd number of negative numbers multiplied give you a negative answer. an even number of negative numbers multiplied gives you a positive answer. this rule only applies to NEGATIVE numbers. for example: (-1)x(-1)x1x(-1)x(-1)x(-1)x(-1)x1x(-1)x(-1)x(-1) sounds pretty hard right? WRONG there are seven negative numbers. seven is an ODD number. so the answer is -1. if there was eight negative numbers the answer would be 1. hope this helps
