That means zero divided by zero is zero, one and infinity. Do you think I could start a new religious cult based on these premises? The Universe is infinite, zero and one.

One track from start to end even if you must return somewhere, miss a turn or advance N squares, etc. as ordained when landing on those given pointsNow set the game on THREE separate, identically-sized, rectangular boards of 3:2 proportions; EACH marked off into 6 squares by a longitudinal centre-line and two cross-lines at thirds length. Label the boards (for this question on the game's geometry) A, B and C. Label each meeting-point of line and edge, 1 - 6, consistently on all 3 boards so every "port" is unique, A1 to C6.Do that with the individual board in landscape mode; 1 on the left-hand end, number clockwise so the RH end is 4, round to 6 at bottom left. All 3 boards the same apart from identity-letter. The track is drawn on these lines such that when one board is set against the othe... less

His cost of production is four-fifths of that amount. What is his profit?"'70s new-math test:"A logger exchanges a set (L) of lumber for a set (M) of money. The cardinality of Set M is 100. The set C of production costs contains 20 fewer points. What is the cardinality of Set P of profits?"'80s "dumbed-down" version:"A logger cuts and sells a truckload of lumber for $100. Her cost is $80, her profit is $20. Find and circle the number 20."'90s version:"An unenlightened logger cuts down a beautiful stand of 100 trees in order to make a $20 profit.
