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

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 entering 'q'.

The options are as follows:

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.
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 from 1 to range. For subtraction and division, both the required result and the number to divide by or subtract will be from 1 to range. The default is 10.
