Upper & Lower Bounds

The video tutorial explains the concept of approximate measurements and the limits of accuracy, introducing the terms upper and lower bounds. It uses a practical example of a baby's weight to illustrate how to determine these bounds. The tutorial then presents a method for calculating bounds by halving the degree of accuracy and applying it to both decimal places and significant figures. The video concludes by summarizing the key points and hinting at the next topic, which involves calculating with bounds to find the largest or smallest possible answers.
