quiz on simple arithmetic
Start an arithmetic quiz
Specify one or more arithmetic [o]peration symbols to get problems on them
Specify a range. Addition and multiplication problems would feature numbers between 0 and range, inclusive. Subtraction and division problems would have required result and number to be operated on, between 0 and range
[-o +-x/ ] [-r range ]
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:
- By default, 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.
- If a range is supplied, 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, will 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.
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 number.'' if doesn't understand what you typed.
