1. pl -1.25 x175
• Add pl and -1.25: 0.00 - 1.25 = -1.25.
• Change the sign of the cylinder: +1.25.
• The axis is greater than 90, so subtract 90 from it: 175 - 90 = 85.

The answer is -1.25 +1.25 x085
2. +1.25 +2.50 x123
• Add +1.25 and +2.50: +1.25 +2.50 = +3.75.
• Change the sign of the cylinder: -2.50.
• The axis is greater than 90, so subtract 90 from it: 123 - 90 = 33.

The answer is +3.75 -2.50 x033
3. -6.75 -2.50 x013
• Add -6.75 and -2.50: -6.75 -2.50 = -9.25.
• Change the sign of the cylinder: +2.50.
• The axis is less than 90, so add 90 to it: 13 + 90 = 103

The answer is -9.25 +2.50 x103
4. +0.25 -0.25 x036
• Add +0.25 and -0.25: +0.25 - 0.25 = 0.00.
• Change the sign of the cylinder: +0.25.
• The axis is less than 90, so add 90 to it: 36 + 90 = 126.

The answer is pl +0.25 x126
5. -3.50 +1.25 x150
• Add -3.50 and +1.25: -3.50 + 1.25 = -2.25.
• Change the sign of the cylinder: -1.25.
• The axis is greater than 90, so subtract 90 from it: 150 - 90 = 60.

The answer is -2.25 -1.25 x060
6. -0.25 +0.50 x089
• Add -0.25 and +0.50: -0.25 + 0.50 = +0.25.
• Change the sign of the cylinder: -0.50.
• The axis is less than 90, so add 90 to it: 089 + 90 = 179.

The answer is +0.25 -0.50 x179
