Hindu-Arabic numerals | History & Facts |

Students will explore the properties of number systems by effectively inventing a base-3 number system using circles, triangles and squares as the symbols instead of arabic numerals. Students are asked to create rules that explain how each arrangement of symbols can be generated or predicated as an orderly, logical series. The objective is to understand that you can represent any number with any agreed-upon set of symbols that appear in an agreed-upon order. This is as true for circles, triangle and squares as it is for the digits , or the number systems we commonly see in computer science binary and hexadecimal. Typically we see numbers represented in decimal base , binary base-2 , and hexadecimal base

A numeral system or system of numeration is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number eleven in the decimal numeral system used in common life , the number three in the binary numeral system used in computers , and the number two in the unary numeral system e. For example, the usual decimal representation of whole numbers gives every nonzero whole number a unique representation as a finite sequence of digits , beginning with a non-zero digit. However, when decimal representation is used for the rational or real numbers, such numbers, in general, have an infinite number of representations, for example 2.
