Parts of Algebraic Expressions

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 + 2y + 7, the constant is 7.

Front

How many terms are in the expression 6a + 4b - 7?

Back

There are 3 terms in the expression: 6a, 4b, and -7.

Front

What is the term used for a letter that represents an unknown number in algebra?

Back

The term is 'variable'. For example, in the expression 2x + y, x and y are variables.

Front

Identify the variables in the expression 2x + y + 8.

Back

The variables are x and y.

Front

What is the '2' called in the term '2x'?

Back

The '2' is called the 'coefficient'.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations. For example, 3x + 5 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 4x + 3y - 5, the terms are 4x, 3y, and -5.

Front

What is a coefficient?

Back

A coefficient is a number that multiplies a variable. In the term 5x, 5 is the coefficient.

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?

Back

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