Not passing tests despite fulfilling user stories

Tell us what’s happening
I followed the user stories for this the JS Calculator project, and I got my calculator to follow the exact behavior needed. But I still failed the test cases (test number 8,9, and 11 to 15). I’ve tried to read the source code of the tests, but I can’t figure out why.
