There are 373 students in a college who have taken a course in calculus, 211 who have take a course in discrete mathematics,
and 161 who have taken a course in both calculus and discrete mathematics. How many students at this college have taken
a course in either calculus or discrete mathematics?
~~~~~~~~~~~~~~~~~~~~~~~~ 

373 + 211 - 161 = 424 student take either calculus or discrete mathematics.
