A teacher asked me about a problem in one of the math textbooks. Is there some rule that I
am not aware of in the order of operations for multiplication and division from left to right?

Here is the problem:

40 ÷ 5(2)

Does the two in parentheses imply that the multiplication is to be done first or is the
problem done L to R with division first? One calculator had 4 for the answer and
another had 16.

Looking forward to your thoughts.
