**ALGEBRA 2: Algebra Multiplication. **

This is an example of algebra multiplication. There are three variables a, b and c, each of which has an associated coefficient (fixed whole number).

First brackets are inserted to expand the equation, before the coefficients and the variables are grouped prior to the final calculation. Remember mixed variables must remain separate.

Brackets help to avoid the confusion of a multiplication and minus sign next to one another. They also ensure the contents are treated as being an associated group i.e. the coefficients can be treated together. The variables are placed outside the brackets as they cannot be grouped.

Note the effect of the minus sign on the bracket contents, i.e. positive × negative = negative.
