Scientific Notation and Linear Functions

Mr. Baskin's math tutorial covers scientific notation, including multiplication and division of terms, and applies these concepts to calculate the number of bucketloads needed to empty the world's oceans. The video also analyzes stock price trends over 28 days, finds the equation of a line through two points, and explains triangle similarity using scale factors and angles.
