How to Use Babylonian Numerals (Clay Tablets)

Our system of using just nine numerals (0,1,2,3,4,5,6,7,8, and 9) to write all our numbers is based on a very ancient tradition! Thousands of years ago, the Babylonians managed to write all their numbers with just TWO symbols! They were able to do this because they used 'place notation' ... that is, the VALUE of a number is determined by WHERE the numeral is written (i.e. in which column, or position). Ultimately, all the better counting systems are based on this idea. Understanding it will help us understand how to add, subtract, multiply and divide our numbers ... and learn some short cuts as well! In this video you will learn how to 'write' Babylonian numerals and how it is that you STILL use this very old counting system every day of your life! I am confident that you will learn something new and interesting! You will also learn a little about our 'place notation' and we will follow up on this in subsequent videos.
