Barry Sovel  
In mathematics, we can use the term 'rule', but in reality, there are no rules, only proofs; therefore, we must be able to demonstrate and prove each mathematical statement and expression before we can apply the tag 'rule' to it. Five such demonstrations that discuss and illustrate the ideas of multiplying and dividing positive and negative values are provided: An Inductive Method; Division Property of One; Positive and Negative Exponents; Number Line/Opposite of; Reciprocals.
