Thank you

java: sample and full tests produce warnings

I also have to question this one, I won't assert that it is definitely wrong but I suspect it is:

-3 * 0 = 0 expected:<0.0> but was:<-0.0>

That's a warning, not an error, it probably does not stop you from doing anything.

Maybe there's more text than that and part of it is an actual error?

Hi,

I am having some trouble. I tried my solution in Java in eclipse and it works, but I am getting this error:
STDERR:
src/test/java/CalculatorTest.java:8: warning: [removal] Double(double) in Double has been deprecated and marked for removal
assertEquals("3.2 + 8 = 11.2",new Double(11.2),Calculator.calculate(3.2,"+", 8));

Thanks

Please DO NOT post solutions in discourse.

Funny and quite mathy kata rather than technical.

oh? so in the case of 0x+b, the kata wouldn't require us to just raise b to the power of n

You can access solutions on the Solutions tab, if you're unable to solve this.

Looking at your current code, why did you move it outside of the function? If you move it back inside, your code might work.

guys whats the answer

Tests do not necessarily test for "-1" being the coefficient of the term with the highest power of the variable (e.g. the x^3 coefficient of (-x+1)^3 is -1). In this case, my original code would have returned -1x^3 + ..., yet it passed because this case was not tested (I ran it again because I removed some print() statements, and then it failed).
Brilliant kata, though—thanks!

Rust sample tests expect the function to be named expand_binomial, but the initial code and the full set of tests expect expand.
