Hi there,

I just have a range of questions in relations to the Chapter 3 from the Maths Section.

1. How do you get the answer for Question 2 without the use of a calculator?

2. How do you get the answer of 3 for Question 7? I have looked at the worked solutions and am still slightly confused?

3. In relation to Question 12, why is In (1) in the question stem? How do you determine the answer being 9 without the use of a calculator?

4. In relation to Question 15, I have looked at the worked solutions however am still confused as to determine that the answer is B. I thought that it may have been -In [A] as per the axis labels?

Thank you so much,

Kind regards and best wishes,

Em Stevens
