Hello,

I am at a loss. Do we include "and" or not? I assumed that we include "and" but I get the wrong sum and I cannot find my error.

I swore I did not have a spelling error until I found a spelling error. I had two "t"(s) in eighteen.

Since spelling matters in this problem, as a lot of us have found out, maybe there should be a reference to the correct spellings?

This was really frustrating, but the final touch came when I enabled spell checking in my code editor. I had "thirteen" spelled wrong. So if you just can't find your mistake, try this.
