In this explainer, we will learn just how to evaluate, simplify, and multiply pure imagine numbers and solve equations end the collection of pure imagine numbers.

Gaining confidence in working v imaginary number will enable us to get the necessary skills to work efficiently with complex numbers an ext generally.

Historically, the advent of complicated numbers to be primarily linked with the idea of fixing equations. In particular, in the 16th century, mathematicians were working to find algebraic remedies to the cubic equation. Intriguingly, the equations mathematicians were trying come solve often had purely real solutions. However, the methods compelled to settle them finished up through the have to evaluate the square root of an adverse numbers. In particular, Tartaglia’s technique for solving cubics of the form
