## What is it

SpeQ is a small, extensive mathematics program with a simple, intuitive interface. All calculations are entered in a sheet. In there you can freely add, edit and execute calculations. SpeQ supports all common functions, constants, and units. Furthermore, you can define custom variables and functions, and plot graphs of your functions.

## Handy!

SpeQ is written to be an advanced but very easy to use math program. It is small and fast and runs on every Windows computer, also from an USB-key or floppy disk. SpeQ is useful for simple, brief calculations as well as working out sheets with extensive variable definitions, functions and complex calculations.

SpeQ is usable for engineers, students and pupils or simply as replacement of the Windows Calculator. ## Features
