Hello, The reason your calculator does not show the answer is because in the if commands, you put for example, you would specify the answer by asking if the string you have entered is equal to the string there, and if so, display its answer, how ever for 1+1e2 for examplem, the person typing the message into the calculator would only type 1+1e because they do not know that 2 is the answer. so take out the answer in the if conissionals to make them 1+1e echo 2
i am not sure why upi have labels for each individual number along with the if.
I actually made a calculator, because i am 13 years old, and it would be cool to have one for nschool (even though I can use calculator in windows). I googled and found you because I wanted to know why my calculator doesn't process decimals.
Try te answer above, or try my calculator which does multiplication, devision, addition, and subtraction.
works with negitives, orders of operation.
I know the set feture does most of the work, but here's the code so you can copy it to a batch script.
Thanks






title Simple calculator
@echo off
:calculate
cls
echo enter a math problem
set /p calc="Problem: "
set /a answer=%calc%
cls
echo %calc% =
echo %answer%
echo.
echo.
echo.
echo to abort, type ctrl+break.
echo otherwise,
pause
goto calculate
