That is not associative, and there are much more formulas a×(b×c) out there than (a×b)×c, so that right-to-left associativity would be natural. I would not advise, however, to rely on operator associativity but to use parentheses. – In algebra, the terms left and right denote the order of a binary operation (usually, but not always, called "multiplication") in non-commutative algebraic structures. A binary operation ∗ is usually written in the infix form: s ∗ t The argument s is placed on the left side, and the argument t is on the right side. Even if the symb…
