The 'Gelosia' method for simple multiplication
The conventional written formal algorithm for multiplication has been taught in schools for many years, and consequently many adults have received this as a taught skill, without any realisation that other methods may be possible, or perhaps even preferable. This paper outlines an alternative method that seems to display some distinct advantages and disadvantages when compared with the conventional method. Starting with an example of the conventional method ('long multiplication'), its strengts and weaknesses are discussed, some alternatives are mentioned, and then the 'Gelosia' method is described. Finally, the advantages of the 'Gelosia' method are listed.
