I've been taking some time to study some of the #mathematics that I learnt in high school and subsequently forgot, and I'm beginning to remember one of the big reasons I found the whole thing rather frustrating: so many #maths resources explain the techniques you can use to achieve certain results, but never bother to explain why these techniques work. It seems that I need proof that a given technique works before I can really trust it, and until then my brain refuses to accept it into the canon.

@bemmesr@mathstodon.xyz More often than not the teacher explains the proof rather than the textbook (which is more an aid to teachers than to be used stand-alone), but I have a few explanations here https://dotnet.social/@SmartmanApps/110968910722113903 such as a proof of Pythagoras, amongst other things. Is there anything you wanted further explaining about in high school Maths?
