    Prove that if a² + ab + b² = 0 then a = 0 and b = 0

    You can use a proof by contrapositive. Your statement is of the form if ##P## then ##Q##. This is a conditional statement. The contrapositive is: if ## not~ Q## then ##not~ P##. Conditional statements are equivalent to their contrapositives. ##Q## is of the form (##A## and ##B##) where ##A##...

    Why fewer women in the realm of science and engineering?

    Women are normally well over 40% of math majors. In this study they are 43%: http://www.ams.org/profession/data/cbms-survey/full-report.pdf There was an MAA study that showed over 40% (probably over 43%) as well. They changed the link to so I can't find it at the moment. This article...
