A side note: the terminology “Algebraic” Notation is a misnomer. It
seems to imply that such notations have something to do with the branch
of math called algebra while other notation systems do not. The reason
the name Algebraic Notation is used because when the science of algebra
was young, around 1700s mathematicians are dealing with equations using
symbols like “+ × =” written out similar to the way we use them
today. This is before the activities of systimatic investigation into
notation systems as necessitated in the studies of logic in 1800s or
computer languages in 1900s. So, when notation systems are actually
invented, the conventional way of infixing “+ × =” became known as
algebraic because that's what people think of when seeing them.
