Tyler Wallace's "Order of Operations - Introduction"

Watch the first  video, which introduces you to the order of operations. Please pay attention to the order in which operations are used and the mnemonic PEMDAS and what it stands for. Note that the video does not make use of the equal sign. Please take a look at Saylor Academy's "Revision to MA001 Video" for a detailed explanation of how to solve the two problems presented in the video.

Then, watch the second video. In this video, you will apply PEMDAS to solving problems by first removing parentheses, simplifying exponents, multiplying, dividing, adding, and subtracting. Please understand that regarding multiplication and division, we perform whichever comes first, from left to right.
