My Calculator

'First number input
Dim Num1
'2nd number input
Dim Num2
'Answer to Num1 Num2
Dim Answer
'continue with another calculation
Dim Continue
'choose what sign to calculate on
Dim Operator
'loop until user input is n
Do until Continue="n"
Operator= inputbox("A,S,D,M")
Num1= Cint(InputBox("Please enter the first number:"))
Num2= Cint(InputBox ("Please enter the second number:"))

If Operator="a" then 
Answer=Num1+Num2
elseif Operator="s" then 
Answer=Num1-Num2 
elseif Operator="d" then 
Answer=Num1/Num2
elseif Operator="m" then 
Answer=Num1*Num2
End if
Wscript.Echo Answer
Continue=inputbox ("Do another calculation y/n?")
loop

Thanks for sharing. Here are some comments:

1) Option Explicit - Get in the habit of using it. Always.
2) Variable Names - Your variable names are meaningful which is good. Putting the type info in the variable name (i.e. strContinue) would be even better.
3) White Space - It may hgave been a fluke of posting to the forum, but using proper indentation will make your code much easier to read.
4) If-then-else - Generally speaking if you are going beyond two blocks in an if-then construct, you should probably consider using a Select-Case construct instead

Awesome thanks for the advice!  will break into the habit.
