de'i li 2002-12-05 ti'u li 19:38:00 la'o zoi. Jordan DeLong .zoi cusku di'e >But look at the example; the tu'o is just like zo'e, with 0 being >the value that is implied. Thus, the rest of your stuff doesn't >follow. va'a is separate from vu'u. va'a is a unary operator, returning the negative of its operand, whereas vu'u is a binary operator, returning the difference of its operands. It only seems like tu'o is 0 in li tu'o va'a ny. because we're used to using the same symbol for va'a and vu'u. The book enjoins us not to confuse them on page 438 (18.6.2). In any case, there are other unary operators which can use tu'o in just the same way, e.g. cu'a. There's no number you could replace tu'o with to get something even remotely understandable in li tu'o cu'a ny. Absolute value simply is not a binary operation. >tu'o broda has to be the same as <something> lo broda, anyway. How is that? Does 'zi'o broda' also have to be the same as '<something> broda'? mu'o mi'e .adam.
