What are the 3 rules for multiplying?

Solution

Many rules exist for different types of multiplication and addition. For addition with real numbers a,b, and c:

The associative rule ensures (a+b)+c=a+(b+c)
The commutative rule ensures a+b=b+a
Property of zero ensures 0+a=a

For multiplication;
The associative rule ensures (ab)c=a(bc)
The commutative rule ensures ab=ba
The distributive rule ensures a(b+c)=ab+ac

These few rules can be extended to negative numbers and fractions, which means that they will be true under division and subtraction. A common rule of division is to not divide by 0.
