I hope you can learn a thing from it. If you have any questions please comment below.

I prefer notepad ++ because it recognizes the code.

I updated it so it can use the previous answer in the next sum. And now it has a brighter white color 0F

Here is my code:

@echo off
title Batch Calculator by ICTrix

color 0F

cls

<p>Hi ICTrix,</p><p>I made a simple calculator that cannot calculate exponents, etc.</p><p>Can you put all the commands together so that I would have an advanced calculator? So that I would be able to calculate exponents, Stuff like 3^4= ... and and so on...</p><p>I am not that good in batch scripting and I don't know how to add those stuff :(</p><p>Here is my code:</p><p>@echo off</p><p>:start</p><p>set /p MATH=Equation?</p><p>set /a RESULT=%MATH%</p><p>echo %RESULT%</p><p>pause</p><p>cls</p><p>goto start</p>
<p>Great introduction to batch programming.</p>
<p>Thnx I appreciate it!</p>
<p>I hope you like the update!</p>
