Parts of an Expression and Combining Like Terms

Front

What is a term in an expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both, separated by addition or subtraction.

Front

What is a coefficient?

Back

A coefficient is a numerical factor in a term that multiplies a variable. For example, in 3n, 3 is the coefficient.

Front

What is a constant in an expression?

Back

A constant is a fixed value that does not change. For example, in the expression 4y + 2, the number 2 is a constant.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable raised to the same power.

Front

What is the expression for combining 3x and -5x?

Back

-2x

Front

Identify the constant in the expression 4y + 2 + x.

Back

Front

What are variables in an expression?

Back

Variables are symbols (like x, y, a) that represent unknown values or quantities.

Front

What is the result of combining -x + 7x - 10 + 4x - 6x + 8?

Back

3x + x - 2

Front

What does it mean to simplify an expression?

Back

Simplifying an expression means to combine like terms and reduce it to its simplest form.

Front

What is the difference between a term and a factor?

Back

A term is a single part of an expression, while a factor is a number or variable that multiplies with others to form a term.
