Just do it by distribution. It's one of the easiest things. Don't panic so much right now or you might kill yourself when you see the error function erf(x)
Algebra is tbf just really easy
It aint bull shit, it's easy if you have someone to help you understand it. Newton and leibniz invented it, or rather discovered it. I find doing integration fun.
Anyways just do integration by parts
Instead if saying e^ipi just do -1
There isn't such thing as made up math. If you mean doing shitty 2+2=5 or 1+1=11 then that is just a sin
It has no end
