Make a calculator in notepad

Make a calculator in notepad? It is possible!

To do this, we will use so-called batch commands. These are the commands that are knocked on that "black window", ie CMD.

First, open Notepad and paste this Code:

@ECHO OFF
color 0a
title Calc
ECHO do-you-know-tech.blogspot.com/
ECHO -----------------------------------------------------
ECHO * = Multiplication
ECHO + = Addition
ECHO - = Subtraction
ECHO / = Division
:loop
echo.
echo -----------------------------------------------------
ECHO [Input expression and hit Enter]
SET /p UDefine=
SET /a UDefine=%UDefine%
ECHO =
ECHO %UDefine%
ECHO.
goto loop

Save it in .bat format and that's it. Like this: Save as > calculator.bat

This calculator does NOT count decimal numbers. That's why I made one, a much more complex that calculates decimals. It has been updated to version 2.2 and a lot of options have been added.
