Sample questions

Question 1 — Easy

Calculate the sum of 3.6 and 4.75.

A) 7.85
B) 7.15
C) 8.11
D) 8.35

Answer: Adding 3.6 and 4.75 gives 8.35. Option A results from misaligning the decimal places and adding 3.6 + 4.25. Option C comes from incorrectly carrying digits. Option D results from subtracting instead of adding.

Question 2 — Medium

The temperature in Canberra one winter morning is -3°C. By midday it has risen by 8 degrees. What is the midday temperature?

A) 11°C
B) -11°C
C) 5°C
D) -5°C

Answer: -3 + 8 = 5, so the midday temperature is 5°C. Adding a positive number to a negative number moves up the number line, giving a positive result here. -11°C results from subtracting instead of adding, and 11°C ignores the negative sign on -3.

Question 3 — Hard

What is the sum of -9 and 4?

A) 13
B) -13
C) -5
D) 5

Answer: -9 + 4 = -5 because you start at -9 on the number line and move 4 places in the positive direction. 13 and -13 come from multiplying or adding the absolute values incorrectly. 5 results from reversing the sign.
