What are like terms in algebra?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

How do you distribute a term across a parenthesis?

Back

To distribute a term across a parenthesis, you multiply the term by each term inside the parenthesis. For example, 5(2 - 7n) becomes 5*2 - 5*7n.

What is the order of operations in algebra?

Back

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.
