Maybe the test was really asking you which was the normal frame of reference. Of course, the direction would also be reversed if you were in the southern hemisphere, or were on a planet that spun the other way, or maybe a planet in a binary star system, etc.
I would expect the intelligent test taker to understand the test was not a trick, and that unstated assumptions mean use the defaults.
As for math, there are many ways to teach math, but 2+2=4 in all of them. It is reasonable to assume it is base 10, not base 3, unless the test said "in base 3".
