I had a student tasked with summing a finite geometric sequence with |r|>1, let's say 1+2+4+8+16. He had apparently forgotten the formula for that, but knew the formula for the infinite series a/(1-r). Good enough he thinks, and sums 1+2+4+... = -1, then subtracts off the excess terms 32+64+128+... = -32, and gets the correct answer of 31.
Get a good look. You might never see another.
I think I could do fairly well with any place I'd frequently been in, and with enough autonomy to get disoriented and reoriented. Some of the houses I've lived in are not much more architecturally elaborate than a shotgun shack, but I could also do my elementary school, most of a middle school, two college dormitories, and most of a university library.
It's my favorite opening move in Wordle like games. Screw you vowel lovers with your AUDIOs and OUTIEs.
The college I graduated from required a year of foreign language for graduation -- actually take it and pass, not just test out of it.
OK, that's not quite true. For some reason, the mathematics department was grouped with the languages for purposes of this requirement, so you could take a year of calculus in lieu of a foreign language if you preferred.
Unless you were a math major. Classes in your major didn't count, so all math majors absolutely had to take a foreign language.
Unless you were a dual major like math-physics. Dual majors could apply classes from both majors towards distribution requirements. I knew several "math" majors who took just enough physics classes to qualify as a dual major for the express purpose of not having to study a language.
Indeed, and would have earned full marks had he said that, or even showed any awareness that his intermediate results were somehow nonstandard.
