How you people study math?

I'm a self study person and would like to hear some suggestions from people who are doing math professionally.

This is how I study.

I usually study the theory part first and try to understand the core concepts and stuff like that and go for the examples and try them all of my own. Most of the time I come to the answer atleast have a idea how to initiate or set up.

But some time I'll have zero idea even after seeing the result that why they start that answer like that to prove something (it is this fact that I'm not able to start a proof by myself is exactly what bothers me each time) It seems they picked it out of blue and never in a million year I'll start with this argument because I don't see why they start with that idea at first place(I attached example below).Then I start to question that is my theory part even good? Do i really understood it? etc. All these just because I don't exactly see/know how to start a proof.

For eg take the one I showed in the pic. I will never start the procedure of taking BC× on both sides even if I give my self a whole day to prove that result.

Is this how people usually study or I'm Missing some core understanding or something?

It really frustrates me.

TIA :)

With the fact that e is not centered idk what do do. I guess i should find a way to locate e in ralotion to the center? DEB should be the same as AEC since they cross eachother. Im just really lost

With 5 is it just 50? Since thats the anlgue that mn cover. 9r does that just apply when its in the circle

All this execrcises seem to be like very simple but i jist dont know T_T

I was solving mean deviation for median but when solving median I came that

20 + 110/14 is 27.86 (AI said) but when I calculate it is 27.85 not 27.86 i asked ai to recheck it but he said “27.86 is correct when rounding the final answer to two decimal places.” is that correct? Or it's ok to write 27.85 exam?
