A Boolean Algebra operation can be related with an electronic circuit in which the inputs and outputs corresponds to the statements of Boolean algebra. Though these circuits may be complicated, they ...

One of the basic theorems in universal algebra is Birkhoff's variety theorem: the smallest equationally axiomatizable class containing a class K of algebras coincides with the class obtained by taking ...

This is a preview. Log in through your library . Abstract We present in this paper an axiomatization of Belnap and Perloff's stit theory (a logic of "seeing to it that") with a single agent. The idea ...

Way back before the days of microcomputers, a few very lucky students first got their hands wet with microcomputer trainers. These simple devices used common logic chips, lights, and switches to ...

Millions of high school and college algebra students are united in a shared agony over solving for x and y, and for those to whom the answers don't come easily, it gets worse: Most preschoolers and ...

Includes updates and/or revisions. The influence of a federal report calling for a more orderly approach to teaching mathematics in the early grades will hinge largely on whether its message is ...
