NAME
       arithmetic -- quiz on simple arithmetic

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

DESCRIPTION
       arithmetic asks you to solve problems in	simple arithmetic.  Each ques-
       tion  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 +-x/	 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 addition, subtraction, multiplication, and	division,  re-
		 spectively.   If  you	give one of these characters more than
		 once, that kind of problem will be asked correspondingly more
		 often.

       -r range	 If a range is supplied, arithmetic selects the	numbers	in its
		 problems in the following way.	 For addition and  multiplica-
		 tion, the numbers to be added or multiplied are between 0 and
		 range,	inclusive.  For	subtraction and	division, both the re-
		 quired	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 in-
       volved, and will	tend to	select those numbers more often	 than  others,
       in problems of the same sort.  Eventually it will forgive and forget.

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

DIAGNOSTICS
       What?  if you get a question wrong.

       Right!  if you get it right.

       Please type a number.  if arithmetic doesn't understand what you	typed.
