Which of the following correctly orders the integers from least to greatest?
A-8, -3, 0, 2
B2, 0, -3, -8
C-3, -8, 0, 2
D0, -3, -8, 2
On the number line, further left means smaller. -8 is leftmost (smallest), then -3, then 0, then 2 (greatest). The other options reverse or scramble this order.
Question 2 True / False
-7 is greater than -3 because 7 is greater than 3.
TTrue
FFalse
Answer: False
On the number line, -7 is further left than -3, which means -7 is smaller, not greater. A larger absolute value in the negative direction indicates a smaller number — think of debt: owing $7 is worse than owing $3.
Question 3 Short Answer
A thermometer reads -5°C in the morning and 3°C in the afternoon. How many degrees did the temperature rise?
Think about your answer, then reveal below.
Model answer: 8 degrees
From -5 to 3 is a change of 3 - (-5) = 3 + 5 = 8 degrees. On the number line, this is a move of 8 units to the right. Subtracting a negative is the same as adding its positive counterpart.
