Here is a set of signed numbers: 7, -3, 1/2, -0.8, 0.8, -1/10, -2 Order the numbers from least to greatest.
If these numbers represent temperatures in degrees Celsius, which is the coldest?
If these numbers represent elevations in meters, which is the farthest away from sea level?

-3,-2,-0.8,-1/10, 1/2, 0.8, 7

2)-3 because -3 is by far the coldest in Celsius

3)7 due to being further than zero
