Yeah, we all felt this way at some point - often with a complex function generator like Maths, but perhaps with other modules.
Learning Maths is like learning storecupboard cooking: it is actually lots of separate ingredients (two function generators, the logic, the attenuverters, and the EOC/EOR outputs). Following a recipe is a great way to make dinner but doesn’t always help you get a feel for cooking with ingredients, or making your own things.
I had a look at the Arcade Trill patch, and whilst it’s not so complex, if you just follow the instructions, you will get a modulation output that is somewhat hard to take apart and ascertain what’s going on. But the directions for building it up will give you some clues. It’s a complex LFO, effectively - an LFO modulating another oscillator. It’s a patch that makes sense from top to bottom : start with hearing what CH4 does on its own, and then have a look at what CH1 is doing when the EOC connection is made but not the BOTH one.
A scope helps a little, but so does your ears. Just get a simple square wave or something coming out of an oscillator, and feed the Math CH1 output into pitch CV: it’s really easy to detect changes in pitch, so this is a good place to start seeing what each layer of ‘seasoning’ is doing. Think about which knobs each stage is ‘turning’ via CV, or what is being shaped at what stage.
