I think he needs some general knowledge classes.
One century after the Mayans, around the year 600 AD, Hindu savants invented too the figure "zero". They also invented the position numbering. Arabs learned this figure system from India. They even called them "Indian figures". During the 10th century, these numbers (0,1,2,3,4,5,6,7,8 and 9), slightly changed, were taken over by the Europeans from the Arabs, like many other important items.
