Questions to Ponder:

1. What kind of numbers were used in the problem? Represent the trip of
Princess Sophie and Prince Donald using a number line.
2. What are the opposite numbers on the number line? Can you give some
examples?
3. What does it mean when same distance is travelled but in opposite
directions? How would you interpret it using the numbers -3 and +3?
4. What can you say about the absolute value of opposite numbers say -5 and
+5?
5. How can we represent the absolute value of a number? What notation can we
use?​
