arithmetic — quiz
on simple arithmetic
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
The options are as follows:
- By default,
arithmeticasks 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.
- If a range is supplied,
arithmeticselects 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,
arithmeticwill not ask you to divide by 0.) The default
- is 10.
When you get a problem wrong,
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.
“What?” if you get a question wrong.
“Right!” if you get it right. “Please type a
