I'm so intersted in math and i really love it, and i invented some new methods and i am about to show them for some mathematicians in the US. But the problem i faced is when i started precalculus, i understood everything in the class but when it comes to exam and sometimes homework i make some very silly mistakes. and sometimes choose to answer the question in a hard way while it only works with the simper way. so what is the problem with my way of thinking? and how can i fix it?
