      After finishing up calculus and differential equations taking real analysis was a trip! Basically opening up the box that is calculus and seeing why taking the derivative of a function means dropping the exponent and so much more. It frequently dealt with infinity and we went from writing long equations to solving word problems involving infinite doors. It was great

        Limits are cool 😁 They open the door to all the 20th century maths and physics. I still don’t understand how infinity is treated to get the result that the sum of all natural numbers is -1/12 though. That must use some different definitions, but I’m not sure what.
