 2020-06-23, 23:45 #56 BillyB   Jun 2020 29 Posts let's say: f(x1, y1) = x1 ) y1 = (x2, y2) Remember that I'm using ")" to represent the "cut" x1 = the thing being "cut" y1 = the number of "cuts" x2 = number of pieces after the "cut" or "cuts" y2 = size of the new piece from the "cut" It can also be written as: a ) b = (a(b+1)),(1/b+1) = a Last fiddled with by BillyB on 2020-06-24 at 00:38

For everyone besides the OP, with whom it is clearly useless to attempt to reason: No one has better things to do with their time? Re-read the neverending Don Blazys thread if you like endless natterings involving no new mathematics worth spit and "[it is *so*|it is *not*] division by zero" debates.

BillyB(x,0) = x.
Is this a correct understanding? I am avoiding your 'unmatched-parenthesis' notation, which creates some confusion.

Also, the OP's reporting of Uncwilly's post as "rude" is extremely childish, and far more rude than the post itself. If you're going to be posting er, ah, unconventional ideas to Miscellaneous Math, you had better have the hide of a rhinoceros.
