The Ancient Use of Numbers: Understanding Zero's Journey and Significance

This presentation explores how ancient civilizations utilized numbers, focusing on the pivotal role of zero. Originating from Indian mathematicians, zero traveled to Europe through influential figures like Fibonacci. We compare the limitations of Roman numerals, which could only represent numbers up to 3999, with the flexibility introduced by zero in modern systems. By understanding these historical insights, we gain appreciation for the evolution of mathematics and technology, showcasing the profound impact of the number zero in shaping our numerical comprehension today.

  1. HOW DID THE ANCIENTS USE NUMBERS BY: Chizo Anakwe

  2. INTTRODUCTION • We were given instructions to create a PowerPoint presentation to show people how ancients use their numbers. It was quite hard to find out this information. We also had to answer 5 questions that were about the number zero in general.

  3. Historical facts on the number zero • Zero is the inventions of Indians. Zero traveled over the World due to various travelers from England & UK countries. Zero has unique importance in Math's & Technology. The number zero spread to Europe somewhere in the tenth century. The man that brought the number zero to Europe was called Fibonacci.

  4. Comparison of the number systems Comparing the roman numerals to the new number system These were the normal symbols, but they could only describe numbers up to 3999. The Romans combined their symbols, so VII meant 5+1+1 or seven. This is called a unary system. However, they found that IIII and VIIII were too confusing (for four and nine), so they introduced another idea. If the I comes after the V then you add it (VI is 6). But if the I comes before the V then you subtract it (IV is four). The rule is that you are allowed to add up to three (VIII is eight), but only subtract one (IX is nine). This means that you have to be very careful what order Roman digits are in. XI is a different number from IX.

  5. Introduction of the number zero to Europe The name of the man who brought the number zero to Europe was called Fibonacci. He brought the number zero to Europe.
