It's short for mathematics, not mathematic, damn it. So it should be maths. Because it's plural. Like physics. Or classics. Or physical educationics.
But that's not why I'm here. I take umbrage to (with?) this statement by sozobe:
Or "if worse comes to worse".
There is nothing wrong with this statement. It simply indicates that the person will do something before the state of affairs becomes as odious as it possibly could be, but that the state of affairs is not yet sufficiently bothersome to warrant action. It's a difference in motivation and endurance from the person who would say, "If worse comes to worst.
" In fact, I might argue that if worse comes to worst, the situation cannot be salvaged. If worse comes to worst, all we can do is throw out the carpet, wring our hands, and lament the fact that we did not do something to stem such an unfortunate tide of events earlier.
