![]() Besides writing, they utilized other forms of technology such as wheeled vehicles, boats, plows, weaving, and brick towers known as ziggurats. 2) Cities, writings, and metallurgy were necessary to form this civilization.3 The cities had extensive irrigation systems, codes of law, postal services, and an administrative bureaucracy. The Greeks were originally those who called it “Mesopotamia,” which means, “land between the rivers.” (See the map of the region. This is the area from Baghdad south to the Persian Gulf. Background & Historical Information1 The Babylonian civilization was made up of people who lived in the alluvial plain between the Tigris and Euphrates rivers. We will also look at some of their algebraic techniques, particularly for solving quadratic equations. We will need to come up with new methods of operations for multiplication and division, as the Babylonians did not give us as much information on how they did their calculations as the Egyptians did. As we did with the Egyptians, we will explore the symbols for their numbers, their base system, and their basic methods of doing arithmetic. In this reading, I will use the terms interchangeably, despite the fact that they are not the same. However, Babylon was only a small part of Mesopotamia. While this is its official, scholarly title, it is often referred to as Babylon. Part 1: Introduction to Babylonian Numbers The next civilization that we will explore in this course is ancient Mesopotamia. Real Babylonian Algebra Problems From Tablets. ![]() Practice and Application of the Quadratic Equation. 61īabylonian Algebra − Solving Quadratic Equations. 61īabylonian Algebra − Systems of Equations. ![]() The Alternate Method of Estimating Roots. 57 MAT107 Chapter 3, Lawrence Morales, 2001 38Īn Alternate Method of Estimating Roots. The Sexagesimal System as Used by the Babylonians. The Babylonian Writing System and Scribal Schools. Part 1: Introduction to Babylonian Numbers. So 784 Um interpret it is how I just said it's 784.MAT107 Chapter 3, Lawrence Morales, 2001 And so what I have written right here, 784 that's actually written in the hindu Arabic system. And when you add them together that gives you The Value of this Babylonian # 784. And then of course four times one is just four. So you do those two separate calculations and then you add them together. So it's a four in the ones place of four times one. Think of the triangles as being like tally marks. Where is it? Well it would be right here. And then for this one this symbol is right here. So really what we have to do is take that 13 Since it's it's in the 60s place Times it by 60. So first let's figure out what does this symbol represent? What is the value? If you take a look at the copy and pasted part it's right here. So instead of taking this Symbol and multiplying by 10 really we're taking this symbol and multiplying by 60 instead. Yeah it's a bit weird writing that down but It's not the 10th place anymore, it's the 60s place. Similar to our current system would be the ones place and the one next to it on the left hand side instead of the tense place. This one the one all the way to the right hand side. We have this position and this position right here. So what we have here is we actually have two positions. Babylonians had this positional system where depending on which position you put the symbol, it stood for a different value. We have the thousands place which is 10 to the third power in a similar fashion. We have the hundreds place which is 10 squared. So if you notice we do count by tens and powers of tents. This was base 60 And then the current one we use a base 10 system. Um so Babylonians, their system was actually a base 60 system. The Babylonians, if you take a look at what we have here, they had 59 separate symbols, 59 of them They didn't use zero. So think of this as we have 10 symbols in our current Hindu Arabic system. ![]() Now our current system has 10 digits, Has 0123456789. So the question is to actually convert this number written here at the bottom in blue, convert it into our current standard system which uses hindu Arabic numerals. For this problem will be taking a look at babylonian numerals.
