The '^' symbol acts as 'to the power of' so that the term "" three to the power of 2 "" can be written as "3^2", which means 3 X 3. Multiplication can be shown by either 'x' or '*'. If variables are present, the * will be used, such as 5x * 3, but if no variables are used, it will be written as 5 x 3.
