MikeThe new thing would be to type it into Google and see what that gives, because it does correctly give 10. I suppose people would assume Google is wrong too though…

BlaiseTotally going to try this! Is it depressing or hilarious? I can’t decide.

MikeActually, 10+10×0 is technically undefined. The commutative and associative laws of addition and multiplication do not specify whether 10+10×0 ought to be interpreted as (10+10)x0 or 10+(10×0). The supposed ‘addition first, multiplication second’ rule is not mathematics but artificial calculator syntax.

Paul CarrWolfram Alpha says 10, but it all depends on the operator hierarchy convention you have chosen…

DavidOkay, I can

understandwhy people would put 0 if left-to-right operations were used. But 20? Seriously?samI actually find it refreshing that most people got it correct. Ignorant people tend to speak first so I am not at all bothered by the comments. The banter might have even saved a few of the innumerate so it was all worthwhile.
