0 is a monomial. The concept of a monomial is that the product containing only numbers and letters (or their positive integer exponential powers) is called a monomial. In the textbook of senior one, there is a supplement next to the concept: the single number is also a monomial. 0 is a single number, so it is a monomial.

In mathematics, monomials and polynomials are unified as polynomials, and monomials are special cases of polynomials. So only polynomials are discussed in mathematical science.

In polynomial, there are two special objects: polynomial of degree 0 and polynomial of degree 0. The former index is 0, and the latter refers to a non-zero number. The 0 polynomial is the only polynomial that does not define the degree.

In middle school mathematics, monomial and polynomial are two concepts. Therefore, the teacher should make it clear that 0 is a monomial, called 0 monomial, which is different from 0 degree monomial; The 0 monomial is the only monomial that does not define the number of times.

Extended data:

Adding a number that is not equal to 0 to a monogram with letters will not result in, because it is impossible to merge similar items.

Simplex There is a plus sign between them. )

The concept of monomial: the algebraic expression composed of the product of numbers or letters is called monomial, and a single number or letter is also called monomial (for example, 0 can be regarded as 0 times a, 1 can be regarded as 1 times a letter with an index of 0, and b can be regarded as b times 1), and the product of fractions and letters is also in this form.
