Discoveries of Charles Babbage in the 1800s are described. Origins of the difference engine, his calculating machine, the principles of computation applied to tables, and the design and construction of his engine are included. (MNS)

Describes a procedure technical writing students can use to test how concerns like segmentation, defining criteria, and paragraph structure may apply to finding an organization for their own texts. Essentially a heuristic, the procedure assumes that a number like three (a control number) is useful in organizing information for any kind of…

Using license plates and telephone numbers for teaching probability ideas involving counting rules is suggested. How each is useful is illustrated in some detail. (MNS)

A method is described for finding the two numbers which will form a linear combination with two given numbers a and b yielding the greatest common divisor of a and b. (DT)

Transform humdrum number study into self-awareness and fun. (Editor)
