arithmetic

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.
