<p>Some clarifications:</p>
<p>Math and art are both in L&S. Majoring in both will get you a single Bachelor of Arts (one diploma) with two majors attached to it. This is called a “double major”.</p>
<p>If you major in two subjects from different colleges (e.g. math from L&S and business administration from Haas), then you get two degrees (two diplomas): a BA in math and a BS in business. This is called a “simultaneous degree”.</p>
<p>You are looking at a double major right now. You only have to satisfy L&S college requirements once, but the upper div coursework can overlap in at most two courses (not that it matters in your case). With some careful planning, it is entirely doable, but you may want to take the classes first before you decide.</p>
