Re: Quotation concerning rational arithmetic

Stoutemeyer left out two very important classes of arithmetic
which was taught in elementary school (I go back to the old days
when the new-math was the "in thing", would have been great if
the teachers understood it of course), these are:
(1) integer arithmetic modulo N. 
(2) Boolean arithmetic, including those "sets" and "ven diagrams" with
    apples and peaches. (Finite sets of course).

With "clock arithmetic" as they called it, you can have a nice consistency
