>>13113030You either do what
>>13113055 suggests or you become the actual undisputed best mathematician and win a field's metal by 30, and get that pop culture fame. This is how normie girls would get impressed. Other than that, it's simply a point about how you're smart, which means little (you may be able to leverage it to make them want your validation on their intelligence, but that's some of that good manipulation you can easily mess up). Even the grand total of 5 girls who are mathematicians, who might actually care that you're smart, have the pick of the other math nerds, and if she only cares about math, she'll want them actual best mathematician and be nearly impossible to impress purely by how good you did a proof.
What you want is to have charisma, and just a general attitude of talking to girls to see which one impresses you. Your math skill is good, but it only goes so far. The only way I can think of is to go to a park, write out some proof about something, and go over to a girl and say something like, "hey, I saw you and thought you were cute, I wanted to draw your picture and really capture your beauty." [Pull out the proof.] "However, I'm a mathematician." [Give her the proof.] Then, start up an actual conversation not about math.
