Is the square root of negative one crucial to the process of finding other solutions? Using the properties of the newly discovered square root of negative one, historical mathematician Bobelli is able to solve Cardan's problem. His method shows the crucial aspect of the need for complex numbers, not only in this particular problem, but also in other mathematical and scientific situations.
