Of course not. Mathematics covers a wide range, and numerical operation is the most basic, which is what we usually call arithmetic. Adding letters is algebra, drawing a picture is geometry, and adding a function will put advanced mathematics into it. What is the knot between function and geometry? Advanced mathematics can learn differential, integral, integral, indefinite integral, definite integral, as well as vector, matrix, combination and a large number of branches. How can it only be numbers? If a lot can be summed up as operations, then reasoning is also an important part of mathematics, as well as logic, in short, countless.
