What is the significance of the distributive property in multiplication?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside parentheses.

Front

How do you simplify an expression with multiple operations?

Back

To simplify an expression with multiple operations, follow the order of operations (PEMDAS) to perform calculations step by step.
