My family was very powerful in Bologna, but Pope Julius II exiled my family and executed my grandfather...so I had to change my name in order to return to Bologna.
I received no college education, rather I was taught by Pier Francesco Clementi, an engineer-architect.
The algebras by leading mathematicians of my day were unsatisfactory in providing a careful, thorough exposition...being convoluted treatises that only mathematicians could comprehend.
My recourse: I wrote a self-contained algebra that was to be understable by anyone.
Many historians credit me with the invention of complex numbers, as I was the first to establish definite rules for operating with +i (“plus of minus”) and -i (“minus of minus”) and used them to solve equations via the methods of del Ferro/Tartaglia.
