Marcus du Sautoy uses combinations of peaches and plums and a set of scales, to show how simultaneous equations can be solved. This method didn’t appear in the West until the 19th century, but ...

A numerical solution of the quadratic matrix equations associated with a nonsingular M-matrix by using the alternately linearized implicit iteration method is considered. An iteration method for ...

This method didn’t appear in the West until the 19th century, but had been in use in China centuries earlier. The Chinese could also work with more complex problems, using their remainder theorem.
