Palladio The Arithmetic Mean. "....let the room to be vaulted be twelve feet long and six broad; add six to twelve and it will make eighteen, the half of which is nine; the vault ought therefor to be nine feet." In an Arithmetic Mean, the second amount exeeds the first by the same amount as the third exeeds the second, as in 2:3:4. Three exeeds two by the same amount that four exeeds three. Or, in Palladio's example: 9 exeeds 6 by 3, which is the same amount by which 12 exeeds 9. Practically, this means taking the length and adding it to the width, then dividing the result in half, as Palladio described.

Math Forum K-12 Math Puzzles Problems of the Week Student Center For many years mathematicians, scientists, engineers and others interested in mathematics have played "year games" via e-mail and in newsgroups. We don't always know whether it is possible to write expressions for all the numbers from 1 to 100 using only the digits in the current year, but it is fun to try to see how many you can find. This year may prove to be a challenge. As with many games, the rules for the Year Game can vary slightly. Teachers may wish to use different rules in their own classrooms. This Web page is intended for students in grades three through twelve with a general knowledge of mathematics. ^ (raised to a power), sqrt (square root), and ! (factorial), along with grouping symbols, to write expressions for the counting numbers 1 through 100. This year we will also allow the use of decimal points and double-digit numbers. Please read and follow the rules carefully if you wish to have your solutions posted on this site. Teachers may print out worksheets for students to record their findings, or may print sheets of

87. Quirks In Calculations Index A site exploring shortcuts in arithmetic, investigating the many quirks which arise in addition, subtraction, multiplication and division. http://www.mescall.net/Numbers/index.htm

- QUIRKS IN CALCULATION - The base 10 positional system of notation used for enumeration in the world today is the outcome of a long process of evolution, and provides a highly efficient means of working with numbers. Numbers arise from the act of counting. Many systems have been developed to record and manipulate numbers, but the underlying concept of number itself remains constant. For Plato, numbers existed as objects in a transcendental realm, there to be discovered through reason. If this is not so, numbers must be the outcome of a process of spontaneous intellectual construction as perception moves through space and time: if numbers are created in this way, then attempts can be made to define them in terms of set theory – leaving set theory rather than numbers as a priori truth. While a satisfactory definition of the exact nature of number may be elusive, in a practical sense what defines numbers is the architecture that holds them together. The numerical architecture used today represents the convergence of three distinct elements: Indo-Arabic characters positional notation system (columns right to left representing progressive powers of 10) primacy of base 10 This system of articulating and recording numbers itself gives rise to a variety of patterns and interrelationships which can be used in practical calculations.

L-FUNCTIONS AND ARITHMETIC A 6-month research programme at the Isaac Newton Institute for Mathematical Sciences (University of Cambridge, United Kingdom) January to June, 1993 Organisers: B. Birch (Oxford), D. Blasius (UCLA), S. Bloch (Chicago), J. Coates (Cambridge), J.-M. Fontaine (Orsay), R. Heath-Brown (Oxford), K. Kato (Tokyo). NEWSLETTER 2 January 1993 Background The Isaac Newton Institute for Mathematical Sciences is a new international research centre, sponsoring six-month visitor programmes in topics across the spectrum of mathematical research. At any one time the Institute's new building can accommodate around 20 visitors in each of two topics, with larger numbers visiting for short periods, especially in connection with workshop and conference sessions. Participation will be mostly by invitation, but enquiries are welcome, especially from postdoctoral research workers. The parallel programme will be on Epidemic Models. Theme of the programme Over the last thirty years, number theorists have come to realise that the mysterious connexions between arithmetic problems and the properties of zeta and L-functions, initially discovered in the first half of the nineteenth century, are far more extensive than had been imagined earlier. A vast web of overlapping conjectures has now been formulated, stretching from the Riemann hypothesis and Fermat's last theorem to the Tamagawa numbers of motives. The programme will bring together mathematicians from arithmetical algebraic geometry, automorphic forms, and classical analytic number theory, to work on several of these conjectures.
