6,576 PointsI can't figure out the answer to what should be a simple question. What does the O in 'Big O' stand for? Its not "order"
The answer is not the following: "order", "order of", "order of complexity", "order of magnitude of complexity"

8,031 PointsI was wondering this as well. He says "order of magnitude of complexity" in the video at 4:16. From the transcript:
4:16 The O comes from order of magnitude of complexity.
4:20 So that where we get the big O from.
