What result do you get when you simplify this expression? I get 13, but my son insists it is 4.

= 16 - 6 * 2

= 4

Although multiplication and division has the same rank - it needs to be carried out left-to-right.

Ahhhh, aren't calculators nice?
It really is too easy mess up and get the "13" result by hand!

This is one of the reasons why I replied with "duplicate post".
It is important that everyone (students and teachers) see all the dialog.
Having three different places would make a possibility of someone not seeing Ultraglide's excellent post.

Yes, it's a duplicate, but it touches on an important topic - operator precedence (aka PEMDAS) that many students have trouble with.
