@LukeAlmighty @iamtakingiteasy @beardalaxy No, the answer is 30. I shouldn't even have to explain this.
x is declared to be an initial value of 23
"x = x +7" is adding 7 to the value of X
23 + 7 = 30
that's all there is to it.
The "trick" is that in some fields, the second part is a comparison test and should return a true or false result. But it's intellectual jewry and just meant to fuck with the average person who does not use that nomenclature when doing everyday math, so that is why it is invalid anywhere outside of the academic setting it originated from.
