Understanding Terms in an Expression

What are Terms?

In mathematics, a term is a single number, variable, or the product of numbers and variables.

Terms are combined using mathematical operations such as addition, subtraction, multiplication, and division to form expressions.

Types of Terms

• Constant terms: Contain only numerical values, e.g., 5, -2.14
• Variable terms: Contain variables, e.g., x, y, a
• Coefficient terms: Are products of a numerical value and a variable, e.g., 3x, -2y

Examples of Terms

The following are examples of terms:

• 7
• -10x
• 2.5y^2
• 0.25x

Identifying Terms in an Expression

To identify the terms in an expression, follow these steps:

1. Separate the expression using mathematical operations.
2. Identify the constant terms, variable terms, and coefficient terms.
3. Terms separated by addition or subtraction signs are distinct.
4. Terms separated by multiplication or division signs are combined.

Example:

The expression 5x + 2y – 3 has three terms:

• 5x (coefficient term)
• 2y (coefficient term)
• -3 (constant term)

Conclusion

Understanding terms is essential for manipulating and solving mathematical expressions.

By identifying and classifying terms, you can simplify expressions, solve equations, and perform various mathematical operations.
