Ohm's law is the most basic of fundamentals that you'll need. You'll also want to know about Kirchoff's laws of voltage and current. To really get a grasp on your capacitors and inductors, you'll want some prerequisite knowledge of differential equations, but if that's too much for now, you can also try just getting a multimeter and experimenting with the voltage response across the circuit elements over time. I suggest that you look up an electronic circuit book for beginners and go from there.

Once you're up there in your understanding, buy more pieces than you'll need so you can afford to pop some with your fumbling, and CHECK THE SPECIFICATIONS. You will not find an ideal diode, an ideal MOSFET, an ideal anything. You want to check to make sure that all your parts pull the amperage and the voltage that they're supposed to. Also, logic elements like AND gates and XOR gates are usually best built yourself if they're in line with the elements that need to be powered. You don't want to be sending your main power through a compact one-piece AND gate that outputs 2 milliamps when you're wanting that same line to go to a 3-amp motor later on. However, that's all after you have an academic understanding of basic electronic circuitry. The equipment that you use will make a difference when you're wanting to build an actual circuit.

>learning the math because just by plugging in numbers in equations
Yeah, good luck doing that with differential equations.
