Yes,, Maths is a language.Language is a means of communication. You can communicate via dance, music, words, numbers, light, sound, fire, etc. Whatever means you use, to communicate, is a language. Sex is a language. Romance is a language. Now, the number of persons who can understand a given language is always limited. It may be 1 person or 1 million or more. But there’s a limit.People think of numbers and operations when they think of Maths. But Maths is far more than that. For that matter, there is a wide — practically infinite — range of TYPES of numbers and TYPES of operation. But put that aside, for a moment. You can’t see, without Maths. Your brain calculates distance, light, perspective, etc. without your even being aware of it. The most advanced computers in the world — in combination, and with unlimited financial resources — can’t catch a ball thrown randomly. The maths involved is too complex. A child, however, can do it — with ease. The ball, in a way, is talking to the child. The child’s brain understands the language of the ball’s movemement.Similarly, you can’t read without Maths. Translating marks into letters into words into ideas into speech into memory into understanding into analysis into expression, involves Maths.Basically, Maths is an element of communication AND a mode of communication. But it is not, by any means, the ONLY or even the most important aspect of communication. Maths is one type of language. It is not the only type of language or the best type of language (best is always subjective). But it is surely a language.
