SpeQ Mathematics

(small, extensive mathematics program)

Version: 3.0
OS: Windows 95, 98, ME, 2000, NT, XP or Vista
Release: June 25, 2007 Introduction

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 all calculations. You can define variables and functions, and plot graphs of your functions. You can save your calculations for later re-use.

Objective

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 usefull 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.
