Answer key · Set A
Opposites
1-4 The dot is 4 steps to the left of zero, so it is negative 4.
2-3 The dot is at 3. Its opposite is the same distance from zero on the other side: −3.
37 The opposite of −7 is the number the same distance from zero on the other side: 7.
4B Opposites are the same distance from zero on opposite sides. In B both dots are 3 away.
56 An opposite is the same distance from zero, on the other side: 6 units to the right.
6True Flip once to 6, flip again and you are back at −6.
71/2 Two flips across zero bring you back to where you started: 1/2.
8-0.75 The opposite is the same distance from zero on the left: −0.75, which is −3/4.
91-B, 2-C, 3-A, 4-D Change the side of zero and keep the size.
100 is its own opposite Zero is 0 away from zero on both sides, so its opposite is itself.
11False The opposite of −9 is 9, so −(−9) = 9.
125 B is at 2.5. A is 2.5 left of zero and B is 2.5 right of zero: 2.5 + 2.5 = 5.
