NAME    [Toc]    [Back]

     arithmetic - quiz on simple arithmetic

SYNOPSIS    [Toc]    [Back]

     arithmetic [-o +-x/] [-r range]

DESCRIPTION    [Toc]    [Back]

     arithmetic asks you to solve problems in simple  arithmetic.
Each question
 must be answered correctly before going on to the next.
After every
     20 problems, it prints the score so far and the time  taken.
You can quit
     at  any  time by typing the interrupt or end-of-file character.

     The options are as follows:

     -o      By default, arithmetic asks questions on addition of
numbers from
             0  to 10, and corresponding subtraction.  By supplying one or more
             of the characters +-x/, you can ask for problems  in
             subtraction,  multiplication,  and division, respectively.  If you
             give one of these characters more  than  once,  that
kind of problem
             will be asked correspondingly more often.

     -r       If a range is supplied, arithmetic selects the numbers in its
             problems in the following  way.   For  addition  and
             the  numbers to be added or multiplied are between 0
and range,
             inclusive.  For subtraction and division,  both  the
required result
 and the number to divide by or subtract will be
between 0
             and range.  (Of course, arithmetic will not ask  you
to divide by
             0.)  The default range is 10.

     When  you  get a problem wrong, arithmetic will remember the
numbers involved,
 and will tend to select  those  numbers  more  often
than others, in
     problems  of  the same sort.  Eventually it will forgive and

     arithmetic cannot be persuaded to tell you the right answer.
You must
     work it out for yourself.

DIAGNOSTICS    [Toc]    [Back]

     ``What?''  if  you  get a question wrong.  ``Right!'' if you
get it right.
     ``Please type a number.'' if arithmetic  doesn't  understand
what you
