SpeQ is a small royalty-free math program with a simple, intuitive interface. Details can be found on the developer’s website. There you can freely add, edit and perform calculations. SpeQ supports all common functions, constants and units. In addition, you can define custom variables and functions and plot your functions.

Simple mathematical application for calculations. SpeQ Mathematics can perform calculations of any complexity, from basic operations to complex calculations. You can use the program’s tools to create any functions and variables, as well as function graphs. All calculations are performed on a single sheet, where you can edit data, add new data or delete unnecessary data. You can save the sheet to continue your calculations on it later. SpeQ Mathematics is resource-efficient and doesn’t take up much disk space. What’s more, you don’t need to install the program, just copy it to your hard drive or flash drive. Thus, it is suitable for engineers, students and schoolchildren.

The key features of SpeQ Mathematics include:

• calculation of expressions with arithmetic, conditional and bitwise operators;
• About 100 built-in mathematical, physical, and conditional constants;
• about 60 built-in functions for analysis, arithmetic, complex numbers, and statistics;
• Ability to declare your own variables and functions for later use in calculations;
• decimal, binary, hexadecimal, and octal calculus systems.
