Error on submission

@TMosh

“All tests passed” refers to the test cases that are built into the notebook.
They are not a comprehensive test of your code.
The grader uses different tests.
Your correct code should work with all of them.

So there are ‘edge’ cases? These are simple maths calculations, please give me an example which should work outside of the notebook tests if this is the case.
