Number Bounds

The video tutorial explains how to calculate the lower bound for the expression e - f, where e and f are given to two decimal places. It covers determining the upper and lower bounds for e and f, and emphasizes the importance of using the correct bounds to find the smallest possible value for e - f. The tutorial also provides tips on practicing bounds calculations and highlights the marks available for correctly identifying and using the bounds.

What values do you need to use to find the smallest range when calculating e minus f?

What is the final answer for the lower bound of e minus f, and how did you arrive at that answer?
