Addition evolved out of a very fundamental desire to count and know the quantity of similar objects we have. As always, and whenever possible, I’ll point you to some interesting places, events and people in the history of mathematics. You will soon realize that even the most basic concepts can be seen in different and interesting ways. In today’s blog, we are going to start a steady and cumulative process of exploring the concepts and techniques of mathematics in an evolutionary way. We add the values of each position and come up with the value for the Babylonian number (C). We first translate the Babylonian digits into a Hindu-Arabic number and we multiply it by the multiplier associated with its position (B). Now let’s use this knowledge to translate a Babylonian number (A). They would leave a space or use a non-numeric placeholder to indicate that no digit was defined for a position within a number.

Although the Babylonians understood the concept of nothingness, they did not have a symbol for the digit or value of zero. The Babylonians defined their numbers by using one or more of the 59 digits from above. The multiplier for the next slots to the left of this column increased by a multiple of 60. The rightmost slot in any number has a multiple of 1. The Babylonians wrote their numbers from right to left. They used just two symbols to define the 59 digits as follows: When the clay was hardened in the sun, the writing permanently became a part of the tablet. They wrote in soft clay tablets using a wedge-shaped reed stylus. The Babylonians used one of the earliest forms of written expression: the cuneiform script. Today, this area of the world is now part of Iraq. This nation existed in the southern region of Mesopotamia between the Tigris and Euphrates River. In today’s blog, we’ll visit another ancient culture and learn how the Babylonian civilization used a sexegesimal (base-60) number system to do math.īabylonia existed from about 18th c. In the blog “ Mayan Numbers,” I showed you how the ancient Mayan civilization created numbers using a vigesimal (base-20) number system. In an October blog “ Decimals,” I showed you how we use the decimal (base-10) number system to generate the natural numbers we use today in math.
