Function Definition: f(x) = x²; would be (x => x*x)
plot(function[, plot_range:list]) -> plot a graph by the given function
F(formula) -> makes a function by the given formula(only accepts formula with x)
abs(x) -> absolute value of x
pow(a, b) -> a to the power of b
sqrt(x) -> square root of x
factorial(n) -> factorial of n
range(start, end, step) -> generates a list from "start" to "end" stepping "step"
summation(start, end, f) -> sums "start" to "end" using a function
factorize(n) -> factor "n"(use with caution, don't use big numbers(n > 1e+5))
isPrime(n) -> shows if "n" is a prime(use with caution, warning is n > 1e+5)
