The Numera Expressions Document
The Expressions document is made for mathematical expressions. Unlike hand-held calculators, most computer based calculators and spreadsheets, Numera lets you work in a word-processor environment with syntax highlighting where you can save your work as files and have multiple documents open at once. The following links will take you to some screen shots that will "give you the idea."
The examples shown below are graduated from the beginning level to more advanced.

Expressions documents can use all of our built-in functions.
Expressions documents can use these standard C operators and bitwise operators.
Various color themes are available for the expressions and results text boxes.
