According to the book's introduction, it was created as a response to Sideways Arithmetic after receiving complaints by students and teachers over the inclusion of the logic puzzles in the story. Like its predecessor, More Sideways Arithmetic is organized into 15 chapters, each of which features a number of mathematical and logical puzzles ...
Tarski's World is a computer-based introduction to first-order logic written by Jon Barwise and John Etchemendy.It is named after the mathematical logician Alfred Tarski.The package includes a book, which serves as a textbook and manual, and a computer program which together serve as an introduction to the semantics of logic through games in which simple, three-dimensional worlds are populated ...
Squaring the circle, the impossible problem of constructing a square with the same area as a given circle, using only a compass and straightedge. [ 7 ] Three cups problem – Turn three cups right-side up after starting with one wrong and turning two at a time.
This is a list of mathematical logic topics. For traditional syllogistic logic, see the list of topics in logic . See also the list of computability and complexity topics for more theory of algorithms .
The Ages of Three Children puzzle (sometimes referred to as the Census-Taker Problem [1]) is a logical puzzle in number theory which on first inspection seems to have insufficient information to solve. However, with closer examination and persistence by the solver, the question reveals its hidden mathematical clues, especially when the solver ...
Four glasses or tumblers are placed on the corners of a square Lazy Susan.Some of the glasses are upright (up) and some upside-down (down). A blindfolded person is seated next to the Lazy Susan and is required to re-arrange the glasses so that they are all up or all down, either arrangement being acceptable, which will be signalled by the ringing of a bell.
Induction puzzles are logic puzzles, which are examples of multi-agent reasoning, where the solution evolves along with the principle of induction. [1] [2]A puzzle's scenario always involves multiple players with the same reasoning capability, who go through the same reasoning steps.
A free logic is a logic with fewer existential presuppositions than classical logic. Free logics may allow for terms that do not denote any object. Free logics may also allow models that have an empty domain. A free logic with the latter property is an inclusive logic.
