Tell me please what’s happening:
I am working on the assigment for arithmetic formatter.
The code seems to work and the solution seems correct, yet the tests returns an error. Could someone tell me what the difference between my answer is and whats expected?

My code so far

    lin1 = ""

Open the browser console, clear it then run the tests, you will see a more detailed output from the tests. Including result is not defined (if you try calling your function this error appears in the terminal)

3

Your variable result is not defined anywhere. I think you meant to use the show_answer variable, which is passed to your function.

Yes. I did it. Thanks everyone for your help
