Monomial: An algebraic expression consisting of the product of numbers or letters is called a monomial, and a single number or letter is also called a monomial.
Polynomial: In mathematics, an algebraic expression consisting of several monomials is called a polynomial. Each monomial in a polynomial is called a polynomial term, and the highest degree of these monomials is the degree of this polynomial. Items without letters in polynomials are called constant terms.
2, the usage is different
Monomial: 0 can be seen as 0 times a, 1 can be seen as 1 times a letter with an index of 0, and b can be seen as b times 1). The product of fractions and letters is also a monomial.
Polynomial: If there is subtraction, subtracting a number is equal to adding its reciprocal.
Extended data:
Any product of letters and numbers is a monomial. In division, dividing by a number is equal to multiplying the reciprocal of this number. A single letter or number is also called a monomial. 0 is also a number and a monomial. If the monomial contains only numeric factors, then its degree is 0.
A formula that associates letters or numbers representing numbers with operational symbols is called an algebraic expression. Algebraic expressions cannot contain "≥", "=" and "
The rule of monomial writing: when the number is multiplied by the letter, the number comes before the letter; The multiplication sign can be omitted as a dot or not written; The formula of division can be written as a fractional formula; Multiply the band score with the letter, and the band score will become a false score.
