I agree, the tests aren't aligned with the instructions so this passes when it should not. There is no check if a or b are numbers as outlined in the requirements

It doesn't pass, so this solution isn't correct

this should not work - as passing a non number into variable b will yield NaN ?

This kata is a Draft, there is no Submit button in those.

I don't have a Submit button after the task was completed successfully. Plese solve this problem.

hey guys, can you explain why this one passes if for example a or b !== 'number'? Isn't that supposed to return us NaN for valid signs?

Pretty interesting ;-D

Ye, I got the same issue.

It's okay, I will do it.

Ik this is a Kata for beginners but I really think you should add more test cases (and a few random ones as well) just to see if the code can handle a variety of inputs properly.

oh, I'm talking about the changes you've made. It has made the kata better and distanced itself from the similar one.

Which one? :D

That's better! :D
