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:
-oarithmetic 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.-rarithmetic 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.
arithmetic doesn't understand what you typed.
