Answers to the spherical equivalent problems.

  1. +8.00 -1.00 x 015

    2.         (+8.00) + (1/2)(-1.00) = +8.00 -0.50 = +7.50
  2. +3.50 +1.50 x 135

    3.         (+3.50) + (1/2)(+1.50) = +3.50 +0.75 = +4.25
  3. -0.50 -1.50 x 008

    4.         (-0.50) + (1/2)(-1.50) = -0.50 -0.75 = -1.25
  4. -1.37 +2.00 x 115

    5.         (-1.37) + (1/2)(+2.00) = -1.37 +1.00 = -0.37
  5. +3.75

    6.         (+3.75) + (1/2)(0.00) = +3.75
  6. pl +0.75 x 010

    7.         (0.00) + (1/2)(+0.75) = 0.00 +0.37 = +0.37
  7. +2.25 -2.25 x 136

    8.         (+2.25) + (1/2)(-2.25) = +2.25 -1.12 = +1.13 = +1.12 (rounded to eighths)
