This is the simplest operation Math•Mate performs. Calculator mode may be turned on by clicking the Modes icon or choosing Calculator in the Mode toolbar. When the calculator mode is on the evaluation icon is displayed to the left of the expression.
In the calculator mode you may use Math•Mate as a simple calculator to evaluate expressions in the following way
If the expression contains variables, e.g. 2*x/y, you may compute the value of the expression under various choices of variable values. In this case you have to
To evaluate the same expression again, just modify any desired parameters and press Start or Enter.
Note: Math•Mate has a special "meta - variable" X which is automatically assigned the value of the last computed expression. It may be used for iteration or just for convenience of computations, allowing to break complicated expression into pieces. If you include the X identifier in your expression, don't be surprised if the next computation of the same expression returns a different value. This is because X has changed its value after the first computation.
