@jannem "His new method to solve polynomials also avoids radicals and irrational numbers, relying instead on special extensions of polynomials called ‘power series’, which can have an infinite number of terms with the powers of x."So power series are a new way to solve polynomial equations??? Not new - hundreds of years old. They don't "avoid" irrational numbers, but they can be used to compute irrational numbers.And so on....
