In the lesson on 5 Feb, we went through the 4 operations of integers:
- recap the concept of operations with number lines (through examples: difference in Peak-Depth, difference of boiling points of liquid nitrogen and oxygen)
- the procedure to carry out arithmetic operations with reference to the absolute value and sign of the numbers
- the use of BODMAS/ PEDMAS/ PEMDAS to guide us in the order of operations

The above would have enable you to better understand the feedback given to part (c).

What you need to do:
Equipped with the knowledge and skill, look at what you did for (d) and comment if the working is correct. If it is incorrect, try to spot the mistake.
