You are prob- ably used to seeing and using the 10 symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 of the base-10 number system we’ve adopted to compute and record numbers. But how much do you know about the origins of the wide range of number systems that exist all over the world? Beginning to count Thousands of years ago there were no numbers to represent quantities. Instead fingers, rocks or sticks were used to represent numbers. There were no clocks or calendars to help keep track of time. Instead the sun and moon were used. There was little need for a numeric system until groups of people formed clans, villages and settlements and began a system of bartering and trade that led to a need for currency. In early civilisations, paper and pen- cils were not available to transcribe numbers. Other methods were invented for means of communication and teach- ing of numerical systems devised of symbols. Babylonians stamped them in clay and the Egyptians painted on pot- tery and cut symbols into stone. Roman numerals One system commonly used today is the Roman numerical system. Roman numerals are used in many ways for instance to represent numbers on a clock face, chapters and pages of books or for the main divisions of outlines. Number system At school you learn and practise mathe- matical concepts using the numerals 0-9, the digits of the decimal number system. The use of this system is widespread. In fact, most things we do in our lives, like solving algebra homework and paying for things, are done with the aid of the decimal number system. While we use the decimal number sys- tem in our maths, computers do not. Every computer processor is made of millions of tiny switches that can be turned off or on. To perform its computations a computer uses a number system that only has two digits: the binary number system. These digits (0 and 1) are called bits and cor- respond to the off/on positions of the switches in the computer processor. Every instruction that a computer exe- cutes is coded in this binary number sys- tem. ● The base of any number system is deter- mined by the number of digits in the system.
