Question 6: Explain why -2 is less than 3 on the number line. Give two reasons.

Answer: Because -2 is to the left of 3 on the number line, and negative numbers are less than positive numbers.

Question 7: Identify the mistake in the following statement: ‘-5 is greater than -2 because -5 is closer to zero than -2.’

Answer: Incorrect; -5 is less than -2 because it is further to the left on the number line.

Question 8: Find the numeric value of the expression: -8 + 5 - (-3).

Answer: 0
