rfant commented on Order of Operations (Algebra1 1_2) In the small window it looks like 15 (plus) 3. View it in full-screen and you will see that it is actually 15 (divided by) 3. It is difficult to tell the difference between the two symbols in the smaller window. Great question though, very observant. 7 months ago
