Next week, be sure to try \(x\) for all problems with such a clarification :)Log in to reply

I actually learn something a little bit different. For example,

Note all "usually"s appearing there, so don't blame me for blindly following the above. – Ivan Koswara · 3 years, 9 months ago

If a value is 'clearly' in the form of a fraction (e.g. expected value, lots of division going on, etc) I often ask in terms of a fraction, even if the answer turns out to be an integer. Though, to be fair, this is much rarer.

If a value is 'potentially' huge (e.g. find the sum of all numbers which satisfy this condition), I often ask for the last three digits. I've received numerous disputes saying that "but the answer must be more than 1000, so you are wrong". – Calvin Lin Staff · 3 years, 9 months ago

A related note, a problem just last week: "Find the sum of all \(a\) satisfying the condition." I got one possible value of \(a\) that was a fraction; everything else were integers. I had the strong urge to dismiss that fractional value by "if that fractional value is a possible value of \(a\), then the answer of this question will not be an integer". – Ivan Koswara · 3 years, 9 months ago

Actually for the second one, it quite often is less than \(1000\), but simply is there to not have you discount the possibility that it is greater than \(1000\) (which can, conceptually, be a huge indicator in problems of the scope you're dealing with)Log in to reply

Okay, I notice the "IF", but why "x" is not the answer? – Selene (Elly) Kirkland · 3 years, 9 months ago

well.. it could've said put x if x is greater than or equal to 0 else put x + 1000.Log in to reply

You can't now that they removed the option to submit problems.Log in to reply

I know i really liked that :(Log in to reply

They want x as the answer in the first place, so why is it NOT the answer? I don't get you. EDIT: Assuming the 'if...' is proven true in the question. – Yuxuan Seah · 3 years, 9 months ago
