ARITHMETIC(6) Games Manual ARITHMETIC(6)
NAME
arithmetic - provide drill in number facts
SYNOPSIS
/usr/games/arithmetic [ +-x/ ] [ range ]
DESCRIPTION
Arithmetic types out simple arithmetic problems, and waits for an answer to be typed in. If the answer is correct, it types back "Right!",
and a new problem. If the answer is wrong, it replies "What?", and waits for another answer. After every twenty problems, it publishes
statistics on correctness and the time required to answer.
To quit the program, type an interrupt (delete).
The first optional argument determines the kind of problem to be generated; +-x/ respectively cause addition, subtraction, multiplication,
and division problems to be generated. One or more characters can be given; if more than one is given, the different types of problems
will be mixed in random order; default is +-.
Range is a decimal number; all addends, subtrahends, differences, multiplicands, divisors, and quotients will be less than or equal to the
value of range. Default range is 10.
At the start, all numbers less than or equal to range are equally likely to appear. If the respondent makes a mistake, the numbers in the
problem which was missed become more likely to reappear.
As a matter of educational philosophy, the program will not give correct answers, since the learner should, in principle, be able to calcu-
late them. Thus the program is intended to provide drill for someone just past the first learning stage, not to teach number facts de
novo. For almost all users, the relevant statistic should be time per problem, not percent correct.
