Importance of Algebraic Symbols:
Algebraic symbols play a very important role in mathematics, because it is the ultimate requirement for performing operations on variables, forming expressions, solving. It can be also assumed as the backbone of mathematics and they form math. To understand any algebraic expression, equations and so on we need algebraic symbols.
Mathematics can not be understood without symbols, formulas and so on.
Like for example to learn how to multiply matrices, we need to see the symbol '*' otherwise we don't understand we need to multiple.
