PCAP objective 1.2 is perform evaluations using the math module, and it is one of the most answerable objectives in either exam - the functions do what their names say. Two things are worth care: there are four different ways to turn a float into an integer and they disagree on negative numbers, and every trigonometric function takes radians, so `sin(90)` is not 1.

Written against the versions above. `math.isclose` arrived in Python 3.5 and `math.cbrt` in 3.11. Everything the syllabus names has been present since Python 3.0 and behaves identically.

One machine, and any shell with Python 3 will do - these exams test the language, not a distribution.
