<p>My husband was a math major in college and eventually got a Ph.D. in math.</p>
<p>He has told me that what I think of as math – I got only as far as a year of calculus and a single statistics course – is not what actually goes on in the curriculum studied by math majors. As you get beyond calculus, math becomes increasingly abstract. Thus, some people who liked math in high school do not like the type of math in the math major (and probably vice versa, except that people who did not like math in high school never get that far).</p>
<p>So planning to major in math is fine, but it might be nice to explore at least one other interest as well, just in case the math major becomes less appealing as time goes on.</p>
