In this lesson I show you how to answer those 'wordy' upper and lower bound exam questions (aka limits of accuracy). I have used the following Cambridge IGCSE exam questions in this video:
Question 1 is from paper 2 0580/23/M/J/21 00:13
Question 2 is from paper 2 0580/21/M/J/20 02:08
Question 3 is from paper 2 0580/22/F/M/20 03:53
Question 4 is from paper 2 0580/21/M/J/21 06:49
Question 5 is from paper 2 0580/23/M/J/22 11:10
