The command mate-calc-cmd is used to execute the command-line version of the MATE calculator. MATE is a desktop environment for Linux distributions, and the calculator is one of its built-in applications.

When you run mate-calc-cmd in the terminal, it opens the calculator in command-line mode. This means you can perform calculations and get the results directly from the terminal, without launching the graphical calculator interface.

Using mate-calc-cmd, you can input calculations, mathematical expressions, or functions, and the calculator will evaluate them and display the result. For example, you can use basic arithmetic operators like + for addition, - for subtraction, * for multiplication, and / for division. You can also use parentheses to group expressions and perform more complex calculations.

Here's an example of using mate-calc-cmd:

$ mate-calc-cmd
> 3 + 4
7
> (5 + 6) * 2
22
> sqrt(25)
5

In this example, the calculator evaluates the expressions 3 + 4, (5 + 6) * 2, and sqrt(25), and displays the results 7, 22, and 5 respectively.

Using mate-calc-cmd is helpful when you only have access to a terminal or prefer using the command-line interface for calculations.
