10 Incorrect. Set B is for strictly imaginary numbers like –7i, 11i, or ½I. Press spacebar. a + 0i 0 + bi 0 + bi a + bi

11 Incorrect. Set C is for strictly complex numbers like 4 –3i, ½ + i, or –3 + 6i. Press spacebar. a + 0i 0 + bi 0 + bi a + bi

12 12 - 3i a + 0i a + 0i 0 + bi 0 + bi a + bi

13 4 a + 0i a + 0i 0 + bi 0 + bi a + bi

14 -5i a + 0i a + 0i 0 + bi 0 + bi a + bi

15 CORRECT! Press spacebar twice. a + 0i a + 0i 0 + bi 0 + bi a + bi

16 Incorrect. Set A is for strictly real numbers like –7, 11, or ½. Press spacebar. a + 0i 0 + bi 0 + bi a + bi

17 Incorrect. Set C is for strictly complex numbers like 4 –3i, ½ + i, or –3 + 6i. Press spacebar. a + 0i 0 + bi 0 + bi a + bi

18 13 a + 0i a + 0i 0 + bi 0 + bi a + bi
