Multiplication Methods and Techniques

The video tutorial explains two methods for multiplying a two-digit number by a one-digit number: the standard algorithm and the partial products method. The standard algorithm involves carrying over digits, while the partial products method breaks down the multiplication into simpler steps without carrying. Examples are provided for both methods using the problems 36 * 5 and 53 * 4.

What is the main topic of the video?

• Addition of two-digit numbers

• Subtraction of one-digit numbers

• Multiplication of two-digit by one-digit numbers

• Division of two-digit numbers

In the standard algorithm, what is the first step when multiplying 36 by 5?

• Subtract 5 from 36

• Multiply 6 by 5

• Add 3 and 5

• Multiply 3 by 5

When using the standard algorithm, what do you do after multiplying 6 by 5?

• Multiply 3 by 6

• Write down 30

• Carry over 3 to the tens place

• Add 6 and 5

What is the result of adding the carried over number in the standard algorithm for 36 * 5?

• 150

• 180

• 200

• 210

What is the first step in the partial products method for 36 * 5?

• Multiply 6 by 5

• Multiply 3 by 5

In the example 53 * 4, what is the first step in the partial products method?

• Multiply 5 by 4

• Multiply 3 by 4

• Subtract 4 from 53

• Add 5 and 3

What is the result of multiplying 3 by 4 in the example 53 * 4?

• 20

• 12

• 15

• 18

How is the tens digit treated in the example 53 * 4 using partial products?

• It is ignored

• It is multiplied by 10

• It is multiplied by 4

• It is added to the ones digit
