# What exactly is a math expression

## definition

### Term - definition

If numbers, arithmetic symbols, brackets and variables appear in mathematical expressions and these are also meaningfully linked, these expressions are called Terms designated.

variable = Unknown = placeholder for a specific number.
Examples of terms

No terms (because meaningless arithmetic expressions):

Under a term mathematicians understand you meaningful expressioncontaining digits, variables, arithmetic symbols and brackets.

e.g .:

### Terms

If there is a number in front of a variable, this is called Pre-number or coefficient designated. This can be any rational number, for example: , , , ...

Instead of a 1, often only the variable itself is written, e.g .:

So coefficient denotes the number that is in front of a variable.

E.g. the coefficient of 8x² is 8

### Term types

According to the number of terms in a term, one differentiates:

Monomials = single term terms

Binomials = two-part terms

Trinome = tripartite terms

Polynomials = multiple terms

Although the article is informative, it does not explain the rules to be followed when simplifying terms. The rules of sorting apply and then there are the signs, etc.
