Combine Like Terms Practice

Front

What does it mean to combine like terms in algebra?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

What is a like term?

Back

Like terms are terms that have the same variable(s) raised to the same power. For example, 3n and 5n are like terms, while 3n and 4m are not.

Front

How do you simplify the expression 3n - n?

Back

To simplify 3n - n, you combine the like terms: 3n - 1n = 2n.

Front

What is the result of simplifying n + n + n?

Back

The result is 3n, as you are combining three like terms.

How do you simplify the expression 10a + 7a + 3a?

Back

You combine the like terms: 10a + 7a + 3a = 20a.

Front

What is the simplified form of 3r + 17r?

Back

The simplified form is 20r, as you combine the like terms.

Front

How do you simplify -2m + 6m?

Back

You combine the like terms: -2m + 6m = 4m.

Front

What is the importance of combining like terms in algebra?

Back

Combining like terms is important because it simplifies expressions, making them easier to work with and understand.

Front

Can constants be combined as like terms?

Back

Yes, constants are considered like terms and can be combined. For example, 5 + 3 = 8.

Front

What is the first step in simplifying an expression with like terms?

Back

The first step is to identify and group all the like terms together.
