Batch scripting is a text file containing a series of commands intended to be executed by the command interpreter. Much like a unix / linux shell script, the purpose of a batch script is to sequentially process a series of commands.

Batch script math (Adding and subtracting in a batch script)

Batch script mathmatical functions



Baed on search traffic, I notice that alot of people are looking for how to add and subtract using a batch script. This is actually really easy.



In the example below I am going to set a base number for the example and then add or increment up the value. You can copy the code below and save it as counting.bat





@echo off

set count=1

set /a count=%count%+1

echo %count%

set /a count=%count%+1

echo %count%

set /a count=%count%+10

echo %count%

set /a count=%count%-1

echo %count%

pause



The result is pretty clear. If you still need more information feel free to leave a message below and I can give a more detailed example.
