Dos batch help

im trying to make a calculator for my first program, and the cmd opens, then instantly closes.

@echo off
echo /p MATH=equation?
echo /a RESULT=%MATH%
echo %RESULT%

PAUSE

Put it at the end.

[Gigabiter]

dude, it closes at the start, i put a pause, at the start, then i tried the end, and it just closes, as soon as the code runs, it flashes then closes

This code works fine for me.

[Gigabiter]

okay, it shows the exact code you/i put in, then in say the pause sentence, then when you press a button, it closes it

[JFischer00]

It may not be doing what you want, but it doesn't close.

[Gigabiter]

what is happening?

 

[Gigabiter]

this is so fucking confusing

 

[JFischer00]

What do you want it to do?

[Gigabiter]

So, I input "10+1" and it outputs "11"?

[JFischer00]

@Gigabiter this should do what you want. I only did adding. I'll let you figure it out and do subtraction, multiplication, and division. Let me know if you can't get it.

calculator.bat

[Gigabiter]

wait wtf? why does that work and no other bat file works at all?

You can't just put "10+1" and expect it to understand.

 

@echo off
SET /p num=enter first number?
SET /p num2=enter second number?
echo
echo 1. add
echo 2. subtract
SET /P M=Type 1, 2 then press ENTER:
IF %M%==1 GOTO ADD
IF %M%==2 GOTO SUB

:ADD
SET /A RESULT=%num%+%num2%
GOTO END

:SUB
SET /A RESULT=%num%-%num2%
GOTO END

:END
echo The answer is %RESULT%
Pause

 This should work i cannot test as i am on a chromebook, however i should not that this does not check if the user has put in a number so will likely crash if you put in a letter.
