<p>Math and Philosophy do go hand in hand- a historic look at mathematicians who were also philosophers (and vice versa of course) shows this. Math major son took several philosophy courses- the required logical thinking appeals to him (btw- math isn’t arithmetic/numbers, higher level courses especially are much more abstract). Son added a computer science major for its practicality (he added the courses he didn’t take just for interest/overlap with math).</p>
