Term in Algebra
A term in algebra is a group of numbers and other mathematical symbols that are multiplied together. It is often the first element in a sum or difference. The + or – sign is usually used to separate the terms of an algebraic expression. Sometimes a term is a single number, such as x2 + 3 or 6m + 7, and other times, it is a product of several numbers, such as 4x+5x. Depending on the type of term, it may be an algebraic expression or a polynomial.

In elementary algebra textbooks, the term is often defined as a product of several numbers. However, it is also possible to use the term as a combination of several constants, variables, or algebraic operations. For example, a term that contains three constants (one positive, one negative, and one positive integer), such as 12n, is known as a numerical coefficient. Similarly, a term that contains two constants (one positive, one negative, one negative integer), such as a2 and bn, is known as a monomial.
Term in algebra is used in formulas, equations, and inequalities. In addition, it is a helpful word for representation in abstract data types. As such, it plays an important role in semantics of abstract data types. Moreover, it is commonly used in the study of generalized arithmetic.
Typically, a term is a piece of an expression. These pieces are sometimes separated by a division or divide. This is done by placing parentheses around the remainder of the expression. Hence, it is important to pay attention to its writing.
When a term is a product of different numbers or variables, it is called an algebraic term. Terms that contain the same literal coefficients are called like terms. On the other hand, terms that have different literal coefficients are called unlike terms.
There are four types of terms in algebra: constants, terms, terms with no numerical factor, and negative terms. Each of these types has its own definition. Constant terms are those that have fixed values throughout the entire term. Likewise, terms without numerical factors have a unit coefficient. Lastly, negative terms are those that have a value less than zero. Usually, these terms are used in equations to represent unknown numbers that are necessary to solve the equation.
Various other terms are also used in algebra. Examples include exponent, base, dth power, and nth root. One of the most important terms is a polynomial. Basically, a polynomial is a continuous function. Other types of algebraic expressions include integral constants, algebraic operators, and irrational numbers.
Often, an algebraic expression is represented in a table. A table is a rectangular arrangement of rows and columns. Normally, an algebraic expression is written in descending order. Although the order may change, this is the most common way. Generally, the higher powers are written first in a polynomial. If a variable is raised to all types of powers, it is referred to as a polynomial.
