I'lintccl liy Adolf Ilcil/.haiisi'ii, Vicniiii. Preface to the Second Edition. .As the few separate copies of the Indian Studies No. Ill, struck off in 1895, were sold very soon and rather numerous requests for additional ones were addressed both to me and to the bookseller of the Imperial Academy, Messrs. Carl Gerold's Sohn, I asked the Academy for permission to issue a second edition, which Mr. Karl J. Trlibner had consented to publish. My petition was readily granted. In addition Messrs, von Holder, the publishers of the Wiener Zeitschrift fur die Kunde des Morgenlandes, kindly allowed me to reprint my article on the origin of the Kharosthi, which had appeared in vol. IX of that Journal and is now given in Appendix I. To these two sections I have added, in Appendix II, a brief review of the arguments for Dr. Burnell's hypothesis, which derives the so-called letter- numerals or numerical symbols of the Brahma alphabet from the ancient Egyptian numeral signs, together with a third com- parative table, in order to include in this volume all those points, which require fuller discussion, and in order to make it a serviceable companion to the palaeography of the Grund- riss.

  • Lecture 2: Arithmetic
    E-320: Teaching Math with a Historical Perspective Oliver Knill, 2010-2017 Lecture 2: Arithmetic The oldest mathematical discipline is arithmetic. It is the theory of the construction and manip- ulation of numbers. The earliest steps were done by Babylonian, Egyptian, Chinese, Indian and Greek thinkers. Building up the number system starts with the natural numbers 1; 2; 3; 4::: which can be added and multiplied. Addition is natural: join 3 sticks to 5 sticks to get 8 sticks. Multiplication ∗ is more subtle: 3 ∗ 4 means to take 3 copies of 4 and get 4 + 4 + 4 = 12 while 4 ∗ 3 means to take 4 copies of 3 to get 3 + 3 + 3 + 3 = 12. The first factor counts the number of operations while the second factor counts the objects. To motivate 3 ∗ 4 = 4 ∗ 3, spacial insight motivates to arrange the 12 objects in a rectangle. This commutativity axiom will be carried over to larger number systems. Realizing an addition and multiplicative structure on the natural numbers requires to define 0 and 1. It leads naturally to more general numbers. There are two major motivations to to build new numbers: we want to 1. invert operations and still get results. 2. solve equations. To find an additive inverse of 3 means solving x + 3 = 0. The answer is a negative number. To solve x ∗ 3 = 1, we get to a rational number x = 1=3. To solve x2 = 2 one need to escape to real numbers. To solve x2 = −2 requires complex numbers. Numbers Operation to complete Examples of equations to solve Natural numbers addition and multiplication 5 + x = 9 Positive fractions addition and

  • The Egyptian Numeration System
    www.wrightmath.info/media/Math 230/The Egyptian Number System.pdf The Egyptian Numeration System Egyptian numerals have been found on the writings on the stones of monument walls of ancient time. Numbers have also been found on pottery, limestone plaques, and on the fragile fibers of the papyrus. The language is composed of heiroglyphs, pictorial signs that represent people, animals, plants, and numbers. The Egyptians used a written numeration that was changed into hieroglyphic writing, which enabled them to note whole numbers to 1,000,000. The system had a decimal base and allowed for the additive principle. In this notation there was a special sign for every power of ten. For I, a vertical line; for 10, a sign with the shape of an upside down U; for 100, a spiral rope; for 1000, a lotus blossom; for 10,000 , a raised finger, slightly bent; for 100,000 , a tadpole; and for 1,000,000, an “astonished man” with upraised arms. Decimal Egyptian Number Symbol 1 = staff 10 = heel bone 100 = coil of rope 1000 = lotus flower 10,000 = pointing finger 100,000 = tadpole 1,000,000 = astonished man This hieroglyphic numeration was a written version of a concrete counting system using material objects, i.e., a “grouping tally system”. To represent a number, the sign for each decimal order was repeated as many times as necessary. To make it easier to read the repeated signs they were placed in groups of two, three, or four and arranged vertically. Project note: The Rhind papyrus and the Moscow papyrus are two ancient Egyptian documents that show the solutions to quite a number of mathematical problems, some practical in nature and some purely investigating the nature of numbers.

By allowing students to work in ways that have meaning for them, teachers can gain insight into students’ developing understanding and give them guidance. Consider the following hypothetical story, in which a teacher poses this problem to a class of second graders: We have 153 students at our school. There are 273 students at the school down the street. How many students are in both schools? As would be expected in most classrooms, the students give a variety of responses that illustrate a range of understandings. For example, Randy models the problem with bean sticks that the class has made earlier in the year, using hundreds rafts, tens sticks, and loose beans. 12 tens 3 rafts 6 beans *Principles and Standards for School Mathematics, p. 86. 123 bben1957x_ch03_123-212.indden1957x_ch03_123-212.indd PagePage 124124 1/3/111/3/11 7:37:547:37:54 PMPM user-f469user-f469 //202/MHDQ254/ben30913_disk1of1/0077430913/ben30913_pagefiles202/MHDQ254/ben30913_disk1of1/0077430913/ben30913_pagefiles 124 3.2 Math Activity 3.1 MATH ACTIVITY 3.1 Numeration and Place Value with Base-Five Pieces Virtual Purpose: Explore whole number numeration concepts with base-five pieces.

  • Egyptian Bingo By: Sasha Reid, Serika Smith, and Vivian Trumblay
    Egyptian Bingo By: Sasha Reid, Serika Smith, and Vivian Trumblay Goals Curriculum Expectations: Grade 6 To teach students about the ancient Egyptian Mathematics: number system ● Number Sense and Numeration, Operational Sense: use a variety of mental strategies to solve addition, subtraction, multiplication, and Materials division problems involving whole numbers ● Introductory script (Appendix A) ● Quantity Relationships: represent, compare, ● One bingo card/ student and enough chips and order whole numbers up to 1 000 000 to fill up each player’s card (Appendix B) ● Mathematical Process Expectations: ● Sheets of paper representing each communicate mathematical thinking orally, Hieroglyph and their Arabic numeral visually, and in writing, using everyday language, a basic mathematical vocabulary, a equivalent, prepared by the teacher variety of representations, and observing basic (Appendix C) mathematical conventions ● Story cards with challenge for when infinity symbol is drawn (Appendix D) Lesson Introduction (5 minutes) ● The teacher will ask students, “What are some things you know about ancient Egypt?” ● Share some of the information in Appendix A. Lesson (10 minutes) ● Give students the opportunity to learn and practice using the Egyptian hieroglyphic number system by printing each Egyptian hieroglyph with its equivalent Arabic numeral on a large sheet of paper. ○ Initially have the Arabic numerals hidden and have students guess what the different hieroglyphs mean; then present with the larger numbers in the base-ten model. ● Once students demonstrate an understanding of the numbers through the ability to show various numbers as Egyptian hieroglyphs, then move onto the bingo game. Activity (15 minutes) ● Distribute bingo cards and golden bingo chips (Appendix B). ● Introduce students to the game and how to use the additional resource provided (Appendix C).

  • Section 4.1 Additive, Multiplicative, and Ciphered Systems of Numeration
    Section 4.1 Additive, Multiplicative, and Ciphered Systems of Numeration What You Will Learn Additive, multiplicative, and ciphered systems of numeration Systems of Numeration A number is a quantity. It answers the question “How many?” A numeral is a symbol such as , 10 or used to represent the number (amount). Systems of Numeration A system of numeration consists of a set of numerals and a scheme or rule for combining the numerals to represent numbers. Types Of Numeration Systems Four types of systems used by different cultures will be discussed. They are: Additive (or repetitive) Multiplicative Ciphered Place-value Additive Systems:An additive system is one in which the number represented by a set of numerals is simply the sum of the values of the numerals. It is one of the oldest and most primitive types of systems. Examples: Egyptian hieroglyphics and Roman numerals. Let’s start with Egyptian heiroglyphics Example 1: From Egyptian to Hindu-Arabic Numerals Write the following numeral as a Hindu-Arabic numeral. Example 2: From Hindu-Arabic to Egyptian Numerals Write 43,628 as an Egyptian numeral. Roman Numerals Two advantages over Egyptian system: Uses the subtraction principle as well as addition principle DC = 500 + 100 = 600 CD = 500 – 100 = 400 Uses the multiplication principle for numerals greater than 1000 Example 4: From Roman to Hindu-Arabic Numerals Write CMLXIV as a Hindu-Arabic numeral. Solution It’s an additive system so, = CM + L + X + IV = (1000 – 100) + 50 + 10 + (5 – 1) = 900 + 50 + 10 + 4 = 964 Example 5: Writing a Roman Numeral Write 439 as a Roman numeral.
