Why not change the conversion of methyl, ethyl and propyl butane in .......... to 1, 2,3,4 alkanes in chemistry? It's hard to remember the order and can't write. Who stipulated this?

There are two kinds of organic chemistry nomenclature, and the traditional nomenclature (also called customary nomenclature) has always been called this. International nomenclature (systematic nomenclature) follows this point.

In other words, A, B, C and Butane were created by early chemical researchers in China when translating foreign works. This was later recognized in international nomenclature. This is internationally recognized. It's called a, b, c and butane, but it's called 1, 2,3,4 alkane. Do it. That's how everyone learns. Just 10 day's work. There is no harm in studying. At least you can't change the rules for yourself now unless you have the ability in the future. Come on! !
