Hi could I please have some help :)

Basically I noticed that although the test case is this: Test.assert_equals(chain(2, [:add, :mult]), 90, "Error: chain function not working properly")

With my code the first test works and when I click submit I get 1 passed and one fails:
Test Passed: Value == 345.30138755410417
Error: chain function not working properly - Expected: -4.244976874098263, instead got: -4.0

But I think it is just because the test case doesn't expect the error string to have that second bit of text.

Sorry if I'm completely wrong! I am super new. But I think my code should work and was wondering if this is the issue?
