Numbers {complex number}| can have real part x added to imaginary part i*y, where y is real number: x + i*y. Complex numbers can solve all polynomial equations, such as x^2 + 1 = 0. Complex numbers are roots of homogeneous polynomial equations with only positive factors: a*x^n + ... + C = 0. For example, quantum mechanics has only positive energy components, and so uses complex-number equations. Because polynomials can approximate all equations, complex numbers can approximately solve all equations. Because they have two independent components, complex numbers have no inequality equations.
