Multiplication Process and Partial Products

This video tutorial teaches how to multiply a three-digit number by a two-digit number using two examples. The process is broken down into three steps: multiplying by the ones digit, multiplying by the tens digit, and adding the partial products. The first example demonstrates multiplying 267 by 25, while the second example covers multiplying 229 by 13. Each step is explained in detail, including carrying over numbers and adding partial products to find the final result.

What is the first step in multiplying a three-digit number by a two-digit number?

• Multiply by the tens digit

• Add the partial products

• Multiply by the ones digit

• Subtract the partial products

In the first step, what do you do after multiplying the ones digit?

• Subtract the carried over value

• Multiply by the tens digit

• Add the carried over value

What is the carried over value when multiplying 5 by 6 in the first example?

• 3

• 4

• 2

• 5

What is the second step in the multiplication process?

• Subtract the partial products

• Multiply by the tens digit

• Add the partial products

• Multiply by the ones digit

When multiplying by the tens digit, what should you do first?
