Apparently, Active Line is only a small utility very similar to the Windows command line, because it allows you to execute any command or program of the system, as well as open any web page by simply typing the corresponding URL.
But it is not these actions that make Active Line special, because it also has calculator functions, since you can write mathematical expressions of all kinds and will offer you the solution.
The mathematical expressions you write in Active Line can refer to predefined functions, such as: 230 + 15 * (23-14) + sqrt (16).
You can free download Active Line 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
