> The OP was about not to type the multiplication sign it > > 6 / 2 ( 1 + 2 ) I agree that was a significant part of the original problem, but I am largely concerned with the evaluation of 6 / 2 *( 1 + 2 ) which the very large majority of posters so far seem to suggest =3D "1" , both when using various languages and calculators. And opinion seems generally to have been that =3D "9" is an error. Which it isn't. >If you type the '*' in between the '2' and the bracket then of course you= get > '9' on iPhone. I'm glad you say "of course" and I'm intrigued that the iPhone gets it right when so many other systems seem to get it wrong. So far nobody seems to want to either support or resile from the =3D "1" answer as correct, after I said it wasn't. Which seems strange Russell --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
