Yes math is hard but the signature algo mostly. The thing here is that I was a C, assembly dev in 2001 and used this a,b,c variable names when software dev where more of a mathematical thing. After 2008 I took some classes at transliteration languages aka coffeescript and there I learned a lot about the importance of producing “literable” source code to avoid having to explain or produce docs apart of the code itself. Math is hard but if you have good variable names and a good procedure it can be much simpler. Good morning 😃
