What are the parts of an algebraic expression?

Back

The parts of an algebraic expression include terms, coefficients, variables, and constants.

Front

Define a term in an algebraic expression.

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both multiplied together. For example, in 4x + 5y + 6, the terms are 4x, 5y, and 6.

Front

What is a coefficient?

Back

A coefficient is a numerical factor that multiplies a variable in a term. For example, in the term 7x, 7 is the coefficient.

Front

Identify the constant in the expression: 5x + 3.

Back

The constant in the expression 5x + 3 is 3.

Front

How do you determine the number of terms in an expression?

Back

To determine the number of terms in an expression, count the number of distinct parts separated by plus (+) or minus (-) signs.

Front

What is a variable in an algebraic expression?

Back

A variable is a symbol, usually a letter, that represents an unknown value. For example, in the expression 2x + 5, x is the variable.

Front

Identify the variables in the expression: 4a + 2b + 7.

Back

The variables in the expression 4a + 2b + 7 are a and b.

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 4, the constant is 4.
