Joshua ZuckerOn the Google one, I can get the rounding error but not the mysterious replacement of 2s with 5s?

Bryan Lee WilliamsI put into Google:

200000000000002-200000000000001

and got

200 000 000 000 002 – 200 000 000 000 001 = 1

That Yahoo question just makes me pity those people.

Joshua Zuckerhttp://www.google.com/search?sourceid=chrome&ie=UTF-8&q=2000000000000000000002-2000000000000000000001 works to give 0 instead of 1. You just need enough 0s.

The Yahoo one is fine, in the sense that order of operations is arbitrary, but not fine in the sense that someone could be a math grad student and not have learned that. Also the “i’ve been researching for two days” makes it a lot more pitiable.

AlThe first one is not a fail, it’s a genuine question; the answer really is 14 unless you put brackets around the 2+3 bit. Then it’s 20. That had me confused for ages as well until I learnt what BODMAS meant.

CJand the commonsense fail goes to Al : P

JohnnyOrder of operations dictates that multiplication is done first, brackets or not – the correct answer is 14.
