Formulas In mathematics, formulas refer to formulas listed when calculating numerical or algebraic expressions, including letters or algebras of numbers and operation symbols (four operations, multiplication, root, factorial, permutation and combination, etc. ). According to the different calculation methods, the formulas are generally divided into horizontal and vertical. Different from expressions, expressions are meaningful expressions that connect data of the same type (such as constants, variables, functions, etc.). ) Use operation symbols according to certain rules.
