The Real Reason It should be obvious that the presentation of the rules of arithmetic given here is just a collection of motivational arguments, not a formal development.

The formal development of the real number system starts with the field axioms. The field axioms are postulated, and then all the other properties follow from them.

The field axioms are The associative and commutative laws for addition and multiplication The existence of the additive and multiplicative identities 0 and 1 The existence of the additive inverse opposites, or negatives and the multiplicative inverse the reciprocal The distributive law All of these are essential, but the distributive law is particularly important because it is what distinguishes the behavior of multiplication from addition.

Namely, multiplication distributes over addition but not vice-versa. So instead, we adopt the following notation for multiplication: Multiplication is implied if two quantities are written side-by-side with no other symbol between them.

If a symbol is needed to prevent confusion, we use a dot. We can also use parentheses to separate factors.The multiplication sign, also known as the times sign or the dimension sign, is the symbol ×.

The different symbols arose through history, and although each new symbol filled a need, the old symbols still had advantages in some circumstances, so they have been retained.

A better way to look at this problem is to demand that multiplication obey a consistent pattern.

If we look at a multiplication table for positive numbers and then extend it to include negative numbers, the results in the table should continue to change in the same pattern. There are a few other ways to show multiplication in algebra.

As you saw when we multiplied coefficients, you can simply write variables next to each other to multiply them. If you wanted to multiply x and y, you could simply write xy.
