A d ig ita l computer performs a d d itio n , sub traction , m u ltip lica tio n ,
d iv is io n , and other more com plex ca lcu latio n s in an arithm etic u n it.
Some computers use D E C IM A L numbers, but most high-speed d ig ital
machines do arithm etic w ith B IN A R Y numbers. A rithm etic is g en erally
done w ith simple addition or subtraction using e ith e r the "s e ria l" or
" p a ra lle l" method. Com plex ca lcu la tio n s are made by doing a series
of additions or subtractions.
Book IV exam ines the Decim al Number System
and from this derives rules for forming any number
system. These rules are applied to the derivation
of the Binary Number System . The Relationships
and rules for converting between Binary and
Decimal Numbers are discussed.
A fte r the introduction to the number system g en erally used
in high-speed dig ital m achines, the Binary A rith m etic Operations
are exp lained and demonstrated w ith appropriate programs for M IN IV A C 601
Book V uses M IN IV A C 601 to demonstrate
how computer functions may be combined to
perform sp e cific jo bs. Examples of computer
app licatio n s are examined under fiv e major headings:
— "Sim ple C om p uter-like D evices Encountered Every D ay"
--"C om puter A p p licatio n s in Business and Industry"
— "Computer A p p licatio n s in S cien ce and the M ilita ry "
— "Computer A p p licatio n s in the Social Sciences"
— "Computer A p p licatio n s in Scien ce Fictio n Film s"
Book V also discusses how computers "read " printed m aterial and understand "computer lan g u ag es."
Book V I contains games w hich may be played using
M IN IV A C 601 as an opponent, partner or re fe re e . These games
are designed for fun w ith M IN IV A C 6 0 1 , but they also
demonstrate important functions of modern high-speed
computers and provide exam ples of special kinds of problem so lvin g .
