<p>Physics calculations are mostly procedural. If you find yourself stuck, then you haven’t understood the equations (or the mathematical manipulation rules) properly.</p>
<p>The same applies to some calculative math (i.e. that which is mostly used in engineering). The only difficulty in math problems comes (especially in “pure mathematics”), when you may be required to “think out of the procedural box”, when you’re tasked by something that requires you to follow certain exact definitions and make conclusions that are not explicit (i.e. you have to figure out something, which is not self-evident, out, rather than be handed them in the questions. The questions include the relevant terminology and possible known details, but it would be then up to you to recall, what that terminology tells and what it implies or can imply in the problem domain.).</p>
<p>But for most part, it all boils down to practice and having adequate knowledge to solve a problem. Struggling is a sign that you’re missing something or trying to “think the wrong way”. In mathematics studying different types/areas of math can help understand other types of math better, because mathematics is by large a huge web of knowledge, where different areas are connected.</p>
