It's a myth that electronics design is math-heavy, because you can do it with pretty much just +-/ and some ² and roots. Even for e.g. filter design you don't actually need to be able to do (or even understand) any of the calculations yourself, because tools automate it away. Analog design with "basic blocks" is pretty straightforward, "free form design" not following basic blocks (usually resulting in part count reductions or performance enhancements) is much harder. The latter is what often produces "trick circuits" which most people cannot analyze on their own and possibly cannot analyze using SPICE.
