Stretch Your Thinking Whether using the Place Nathe Method, or sections Method, the Expanded Notation Method, the same basic steps the Algebraic Notation Metho can be used to multiply a one-digit number by a three-digit number. Put these steps in order by numbering 1 through 3 . Add the partial products. Write the three-digit number in expanded form. Multiply the one-digit number by each of the values in expanded form.

First, write the three-digit number in expanded form. For example, if the number is 432, you would break it down into 400 + 30 + 2. This sets the stage for multiplying each component separately. Next, multiply the one-digit number by each of the values in expanded form. If your one-digit number is 6, you’d calculate 6 times 400, 6 times 30, and 6 times 2. This helps simplify the math and ensures you cover each part of the three-digit number before combining them.
