Swimming is not innate...some people do pick it up easily, others take a couple of times, but I have never heard of anybody who is "unable to learn how to swim" and once they learn they can practice and get very good at it....there is sometimes a genetic advantage (Micheal Phelps springs to mind) - but he wasn't always nearly 7 foot swimming giant, he had to learn different techniques and practice for hour and hours a day to get as good as he is.

I said it multiple times: practice will let you improve in anything but if your genetics is playing against you, you'll face a very steep road.

Actually you started off by saying you can't teach "talent", now you are saying you can teach it but it may be hard...

Do you honestly think your genetics is playing against you in your study of mathematics? Which bits are you struggling with? What have you tried to fix it? What courses have you taken? Have you tried private tutoring? khan academy? Have you tried anything for longer than a couple of a days? weeks? How many hours of deliberate practice do you think you have put into studying mathematics?
