At. 5:40. 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.Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere.
