This is a bit nitpicky, but I was annoyed with the shifting between using "math" and "maths" in the article - it's annoying enough to see "maths" used, having formerly been in the academic math world, but to waffle between the two is just confusing.
it's the standard shorthand for "mathematics" that's used in Australia. We don't use the term "math".
Every example of "math" appears in a quote, so they are being reproduced verbatim.
Maybe the US English uses 'sports' instead of 'sport' due to the conflict in meanings between the two uses.
Just an idea.
