ARITHMETIC(6)		       BSD Games Manual			 ARITHMETIC(6)

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	     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, 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 multiplication,
	     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 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 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.
