Simple mathematical operations

Is it possible to do some basic mathematical operations with Igor? I want to divide one wave to another.
Make/N=10 wave0 // Only numbers
Make/N=10 wave1 // Only numbers
Make Result_wave
Result_wave = wave/wave1 // ??? This won't work!
Is there a way of doing that? I know this is easy with Excel but I need it in Igor. Thanks.
Sincerely,
Emre

That will tell you more than you ever wanted to know about the topic.
Having said that...
Your example has a few problems. First, your Result_wave is made with the wrong number of points. It's easiest to use Duplicate to create a wave with the correct characteristics for receiving the result of arithmetic on waves. And, of course, you misspelled "wave0".
Make/N=10 wave1 // Only numbers
Duplicate/O wave0,Result_wave
Result_wave = wave0/wave1 // ??? This won't work!
Of course, the contents of Result_wave are garbage because wave0 and wave1 were never initialized with anything.
