Why not just use the QUICKCALC built into AutoCAD?
It's also available in the Properties Palette by clocking on an object that has a numeric value in properties when you click on that value it displays an image of a calculator you can click on to use it in the calculator.

There's also the original CAL command

CAL is not in Bricscad V20 maybe later version pops windows calcualtor.

There is some lisp out there that does calculator input you enter as a string and it works out the answer a simple example, 12+13 converted to (+ 12 13) within code, do a google.
