What are Coefficients?
In mathematics, a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression or equation. In other words, it's the number that is attached to a variable.
Examples:
Consider the algebraic expression 3x + 5. Here, 3 is the coefficient of x, and 5 is the constant term.
In the equation 2y - 7 = 11, the coefficient of y is 2.
How to Identify Coefficients:
To identify the coefficients in an algebraic expression or equation, look for the numerical values that are directly next to a variable.
Study Guide:
- Learn the difference between coefficients and constant terms. Coefficients are the numbers that multiply the variables, while constant terms are standalone numbers in an expression or equation.
- Practice identifying coefficients in various algebraic expressions and equations.
- Understand how coefficients affect the value of the variable in an expression or equation.
- Learn to perform operations involving coefficients, such as addition, subtraction, multiplication, and division.
- Practice solving equations with coefficients to understand how they impact the solution.
Understanding coefficients is essential for solving algebraic equations and expressions. Practice identifying them and performing operations involving coefficients to strengthen your understanding of this concept.

Grade 6 Curriculum Focal Points (NCTM)
Number and Operations: Connecting ratio and rate to multiplication and division
Students use simple reasoning about multiplication and division to solve ratio and rate problems (e.g., 'If 5 items cost $3.75 and all items are the same price, then I can find the cost of 12 items by first dividing $3.75 by 5 to find out how much one item costs and then multiplying the cost of a single item by 12'). By viewing equivalent ratios and rates as deriving from, and extending, pairs of rows (or columns) in the multiplication table, and by analyzing simple drawings that indicate the relative sizes of quantities, students extend whole number multiplication and division to ratios and rates. Thus, they expand the repertoire of problems that they can solve by using multiplication and division, and they build on their understanding of fractions to understand ratios. Students solve a wide variety of problems involving ratios and rates.
