Alt1 is a free scientific calculator that will help you perform real time calculations using a wide range of operators and keeping full history of equations. A not so common feature of this calculator is that it misses an “equals” button, your equations are solved in real time, and they are stored in a history you can use later: if you edit equations saved in the history, solutions that are based on these equations are also updated automatically.

Note that you can open more than one instance of Alt1 to solve a lot of problems simultaneously. Using the program’s system tray icon you can get help or start an instance of the calculator.

Alt1 free scientific calculator features a modern minimal interface and it is fast, convenient and reliable, a program you should try if you are in search of a calculator.
