@phi @mathstudent55

OpenStudy (phi):

do you know what i*i is ?

OpenStudy (bluebeta):

-1?

OpenStudy (phi):

yes. and -1 is a real number so the (lousy) joke is if you have a "pure" imaginary number and you multiply it by i you will get a "pure real" number

OpenStudy (bluebeta):

Well.. I feel stupid lol.

OpenStudy (phi):

it *is* a dumb question.

OpenStudy (bluebeta):

LOL yes. Thank you very much!

OpenStudy (irishboy123):

it is not a dumb question it is a joke

OpenStudy (irishboy123):

but you really need a sense of humour to get a joke
