The Calculation dialog is useful tool for performing quick calculations whose results can be copied and pasted throughout Cranium and Synapse.

1	Control in which math expressions are entered.
2	Pressing the Recent button displays a list of all recently calculated expressions. Selecting an expression from this list will copy and paste it into the expression control.
3	List of known mathmatical functions. Clicking the left mouse button on an function will display its documentation in the control to the right.
4	Displays the selected function's documentation.
5	Displays the result of the calculation.
5	Copies the result to the clipboard.
