b. is right. The Mayans developed a sophisticated math system, in which they found value in the absence and gave it a figure to represent it. They also established a combination system of small integrated figures that had the order to express value, very similar to the Arabic system.

c the Incas didn't find value on absence and they created a system of dots and thread to express amount. Their numbers consisted of the combination of dots perforated by lines to express groups and create bigger numbers.
