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 reuse.
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 USBkey 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.

 Expression calculations with arithmetic, conditional, logical and bitwise operators
 Around 100 builtin mathematical, physical and conditional constants
 Around 60 builtin functions for Analysis, Arithmetic, Complex numbers, Hyperbolic, Integers, Probability, Numeral systems, Statistics, Trigonometry
 Define your own variables and functions for use in calculations
 Plot fully adaptable graphs, trace the plotted functions, save your graphs
 Decimal, binary, hexadecimal and octal numeral systems
 Calculations with lists
 Complex number calculations
 Colored workarea
 Save and load sheets
 Orderly overview of all available functions and constants in the Functionstree
 A list with all defined variables and functions in the Memorylist
 Contextsensitive help and a detailed users guide
