### Real Numbers Activity 1: What does it mean to us?

1. If -4 km/h means 4 km/h below the speed limit, what does 12 km/h mean?
2. If -7˚C denotes a temperature drop of 7˚C, what does 5˚C denote?

3. If 20 km denotes a distance of 20 km due east, what denotes a distance of 6 km due west?
4. If 100 represents a gain of \$100, what number represents a loss of \$150?
5. If we use the integer "5" to represent 5 floors above the ground level, what integer is used to represent 2 floors below the ground level?

2. Increase of 5 degrees in temperature.
3. -6km
4. -\$150
5. -2

1. As -4km/h is 4km/h below the speed limit, 12km/h means that it is over the speed limit.
2. It means that there is an increase of 5ºC in temperature.
