Introduction
SpeQ is a mathematics program where you can enter your calculations in a sheet.
It's useful for making simple as well as advanced mathematical calculations, and is designed to be very easy to use.
SpeQ is a small program that runs on any Windows computer.
The interface of SpeQ resembles a colored notepad editor.
Simply enter an expression in the Workarea and press <ENTER> to calculate the answer.
Another expression can be entered on the next line, and you can freely edit all text in the Workarea.
You can save your sheets for later reuse and modification.
If you're new to SpeQ, it's recommend to read the page Getting started to find out what you can do with the program.
