One of my former students who is now starting to teach asked me the
following question for which I don't have a good answer;

On the TI-82: 10/5*2 equals 4

but 10/5(2) equals 1.

The order of operations rules that I've been using for twenty years would
agree with the answer equal to one. Multiplication and division are
"equal" in power and you work from left to right. The parentheses in this
case don't change the order of operations.

Have I missed something? Thought I'd throw this out to the list serve
for any thoughts.

Thanks ,
