Answer key · Set C
Zero, Debts and Depths
1-25 Count back from zero in fives: −5, −10, −15, −20, −25.
2-60 Count back from zero in twenties: −20, −40, −60.
3−7, −1 Numbers to the left of zero are below zero: −7 and −1. Zero is the starting point, and 4 is above it.
42 floors below the street A negative level is below the street, and −2 is 2 floors below.
51-B, 2-A, 3-D, 4-C Below zero and owing are negative. Above zero and saving are positive.
64, 3, 5, 1, 2 The farther below zero, the colder. −12 is coldest, then −3, then −1, then 0, then 5.
7Ana The dot farthest left is the coldest. −8 is farther left than −3 and 2.
8True −3 is left of −1, and −3 is less than −1. Left means smaller.
97 From −7 up to 0 is 7 steps.
10−15 A debt is below zero, so what she owes is −15.
11nearer the surface The fish is 1 meter below the surface, but 3 meters above the bottom.
12True Zero is the starting point between the positive numbers and the negative numbers.
