Sal says that you have to do things from left to right when you have multiple operations at the same level. At this point in the video, the problem is: 10 x 4 / 2 - 5 x 6. Sal solves left to right: 40 / 2 - 5 x 6 = 20 - 30 = -10. But if I don't do it in the same order I get the same answer: 10 x 2 - 5 x 6 = 20 - 30 = -10.

Solve by completing the square: Non-integer solutions. Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
