How to Use Expanded Form to Multiply One-Digit Numbers By 3-digit or 4-digit Numbers
Expanded form is a great way to simplify multiplication problems, especially when you're multiplying one-digit numbers with larger numbers.

A Step-by-step Guide to Using Expanded Form to Multiply One-Digit Numbers By 3-digit or 4-digit Numbers
Here is a step-by-step guide to Using Expanded Form to Multiply One-Digit Numbers Via 3-digit or 4-digit Numbers:
Example: Multiply 3 by 456 (a 3-digit number)

Step 2: Write the larger number in expanded form
The larger number (456) needs to be written in its expanded form. This means breaking it down into hundreds, tens, and ones:
\(456=400+50+6\)
Step 3: Multiply each component by the one-digit number
Now, multiply each part of the expanded number by 3:
\(3\times400 = 1200 3\times50 = 150 3\times6 = 18\)

Step 4: Add all of the products together
Next, add together the products from step 3:
\(1200+150+18=1368\)
So, \(3\times456 =1368\)
Using the expanded form method makes multiplication easier to understand and solve, particularly with larger numbers. It’s an excellent tool for students in grade 4 or anyone looking to develop their basic multiplication skills.
