82. Binary Numbers, Arithmetic, And Radix Conversions we can represent numbers in it; binary arithmetic operations can be implemented using ofnumbers sooner, so it's easier (that's actually a general principle of http://www.cs.nmsu.edu/~pfeiffer/classes/273/notes/binary.html

Binary Numbers, Arithmetic, and Radix Conversions Binary Numbers Computers work as we know them today through a serendipitous interplay of three developments: binary arithmetic boolean logic (developed by George Boole) digital electronics (originally based on relays for telephone company applications) We can represent numbers in binary; we can define the operations of binary arithmetic in terms of boolean logic; and we can implement boolean logic with digital electronics. Without that, computers would (at best) be very different than they are today... Arithmetic in radixes other than 10 Remember that a number actually represents a polynomial: 12,573 means 1*10,000 + 2*1,000 + 5*100 + 7*10 + 3*1. Alternatively, we could write it as It turns out that there's absolutely nothing sacred about our choice of 10 for a number radix a few cultures have used five, pre-Columbians in Central America (the Mayans, for instance) used 20, and the ancient Babylonians used 60 (we've inherited our system of dividing circles into degrees, minutes, and seconds from this). I've seen the claim that the Hebrews used 10 for some purposes and 12 for others, but haven't been able to verify it (but notice that our names for the numbers 11 and 12 don't follow the same scheme as the numbers from 13 to 19, and our division of the day into hours also apears to be a vestige of a duodecimal numbering system). So, instead of 10, we could use 8, 16, 79, 13... as we please. In general, we can define any integer number radix

The network sponsors postdoc positions, visiting researchers and network meetings. The Midterm evaluation meeting is organized by the Leiden team . It will take place at the Lorentz Center in the city of Leiden in the Netherlands in the period June 10-14 2002. This meeting will bring the different nodes of the network together to discuss the present state of the project. In lectures of the researchers from the various nodes we will review the results that we have obtained, and we will outline the plans for the next few years 2002-2004.

version history HOW TO CITE THIS ENTRY Stanford Encyclopedia of Philosophy A B C D ... Z content revised JAN Frege's Logic, Theorem, and Foundations for Arithmetic Frege formulated two distinguished formal systems and used these systems in his attempt both to express certain basic concepts of mathematics precisely and to derive certain mathematical laws from the laws of logic. In his Begriffsschrift of 1879, he developed a second-order predicate calculus and used it both to define interesting mathematical concepts and to state and prove mathematically interesting propositions. However, in his Grundgesetze der Arithmetik of 1893/1903, Frege added (as an axiom) what he thought was a distinguished logical proposition (Basic Law V) and tried to derive the fundamental theorems of various mathematical (number) systems from this proposition. Unfortunately, not only did Basic Law V fail to be a logical proposition, but the resulting system proved to be inconsistent, for it was subject to Russell's Paradox. Although the inconsistency in Frege's Grundgesetze is widely known, it is not very well known that a deep theoretical accomplishment can be extracted from his work. The

99. Matrix Arithmetic Matrix arithmetic. We present three interactive webbased demonstrationswhich help teach students the basics of addition, subtraction http://www.cogs.indiana.edu/software/linalg/linalg.html

Home General Academics People Matrix Arithmetic We present three interactive web-based demonstrations which help teach students the basics of addition, subtraction, and multiplication on matrices. In virtue of their instant feedback and self-paced nature, they are ideal learning tools for anyone who wishes to learn the concepts involved through directed practice. We recommend them especially strongly for use with non-majors, or for courses with a primary focus other than mathematics. Matrix Addition and Subtraction This program allows the user to choose the dimensions of the matrices to be operated upon, and input integer values for each cell. The user then chooses to add or subtract the matrices, and the program automatically displays the result. By comparing the final values with those in the intial matrices, the user is able to see the effects of matrix addition and subtraction in as many concrete examples as s/he desires. Stepwise Matrix Multiplication Because multiplication for matrices is significantly more complex than addition/subtraction, this demonstration uses a particular example to show the user every step in the process separately, and does not progress to the next step until the user opts to do so. By using visual cues to highlight the significant portions of the input, the program manages the user's attention in a helpful manner. Matrix Multiplication To test the user's understanding of the processes demonstrated in the previous program, this one allows the user to enter matrix dimensions and values, but then requires the user to perform the calculation. If the user errs, the erroneous entries in the final matrix are highlighted by the program, which then recommends that the user try those cells again. The user may continue to use this practice tool to get immediate feedback on her/his performance until mastery is achieved.
