Create A Virtual Calculator.

 Create A Virtual Calculator

This hand-coded calculator is more a cool proof-of-concept than something I would honestly recommend for your number-crunching needs. Your PC or phone most likely comes with a more intuitive virtual calculator, as does the browser you're probably reading this on. (Via Instructables)

👉Paste the following into a Notepad doc:

@echo off

title Batch Calculator by seJma

color 1f

:top

echo --------------------------------------------------------------

echo Welcome to Batch Calculator

echo --------------------------------------------------------------

echo.

set /p sum=

set /a ans=%sum%

echo.

echo = %ans%

echo --------------------------------------------------------------

pause

cls

echo Previous Answer: %ans%

goto top

pause

exit

👉 Save as a .bat file.

👉Math away. Note: it can only handle integers. And only those of a certain number of digits. It also doesn't handle complex equations all that well. But other than all that, it's just fine.
