Parts of An Algebraic Expression

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 2y + x + 8 + 7p, the constant is 8.

Front

How many terms are in the expression 3a + 2b + c + 100?

Back

There are 4 terms in the expression: 3a, 2b, c, and 100.

Front

Identify the variables in the expression 3x + 9.

Back

The variable in the expression is x.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in the expression 4x, the coefficient is 4.

Front

How many terms are in the expression 3x + 2y + z?

Back

There are 3 terms in the expression: 3x, 2y, and z.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations. For example, 2x + 3 is an algebraic expression.

Front

What is 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. For example, in 5x + 3y, 5x and 3y are terms.

Front

What does it mean to simplify an algebraic expression?

Back

To simplify an algebraic expression means to combine like terms and reduce it to its simplest form.

Front

What are like terms in an algebraic expression?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms.

Front

What is the degree of a term in an algebraic expression?

Back

The degree of a term is the exponent of the variable in that term. For example, in 4x^2, the degree is 2.
