NAME
arithmetic - quiz on simple arithmetic
SYNOPSIS
**arithmetic [ **-o +-x/ **] [ **-r range **]**
DESCRIPTION
*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
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 *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 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.
