## Multiplying Tens – Introduction

In this text, we will explore multiplying tens. This helps us understand larger numbers better. Together, we will practise solving multiplication problems involving tens.

## Understanding Multiplying Tens – Explanation

Multiplying tens involves multiplying numbers where at least one of the numbers is a multiple of ten, like 10, 20, 30, and so on. The key to solving these problems is to multiply the non-zero digits first, and then add the appropriate number of zeros at the end.

For instance, when multiplying 2 by 40, you:

• 1.) Multiply the non-zero digits: 2 x 4 = 8.

• 2.) Insert the zero from the tens place: 80.

Let's break down the steps in more detail:

Step # Action Description
1 Identify the non-zero digits Look at the numbers you are multiplying and ignore the zeros for now.
2 Multiply the non-zero digits Multiply the digits without considering the zeros.
3 Insert the zeros back Count the total number of zeros from the numbers you multiplied and place them at the end of your product.
What is 3 times 20?
What is 4 times 30?
What is 5 times 40?

## Multiplying Tens – Example

Let's solve a problem step-by-step.

Problem: What is 2 times 40?

Solution: 1. Identify the non-zero digits: 2 and 4. 2. Multiply these digits: 2 x 4 = 8. 3. Insert the zero from 40 to the product: 80.

So, 2 times 40 equals 80.

## Multiplying Tens – Guided Practice

Let's go through another problem together.

What is 2 times 20?

## Multiplying Tens – Application

Problem: What is 6 times 30?

Solution

### TranscriptMultiplying Tens — Let's Practise!

Razzi says get these items ready because today we're going to practice Multiplying Tens. It's time to begin! Solve two times forty. Pause the video to work on the problem and press play when you are ready to see the solution! Write zero in the ones place, for the place holder. Two times four equals eight. Two times forty equals EIGHTY. Did you also get eighty? Let's tackle the next problem! Solve three times twenty. Pause the video to work on the problem and press play when you are ready to see the solution! Write zero in the ones place. Three times two equals six. Three times twenty equals SIXTY. Did you also get sixty? Here comes the next problem! What is six times thirty? Pause the video to work on the problem and press play when you are ready to see the solution! Write zero in the ones place. Six times three equals eighteen. Six times thirty equals one hundred and eighty. Did you also get one hundred and eighty? Let's tackle the final problem! Solve eight times fifty. Pause the video to work on the problem and press play when you are ready to see the solution! Write zero in the ones place. Eight times five equals forty. Eight times fifty equals four hundred. Did you also get four hundred? Razzi had so much fun practicing with you today! See you next time!

• ### Multiply and answer the questions.

Hints

The first step when multiplying tens, is to always write down the 0 in the final answer.

The hundreds place is the red box.

The tens place is the blue box.

The ones place is the green box.

The placeholder always goes in the ones place.

Solution

1. 0 is the placeholder which goes in the ones place of the solution.

2. 3 x 4 = 12. The 1 goes in the hundreds place and the 2 goes in the tens place of the solution.

3. So the final solution is 30 x 4 = 120.

• ### Do you know all the steps to multiply by tens?

Hints

The first step is to fill in the placeholder.

When multiplying tens, what number will always be the placeholder?

Remember:

The red box is the hundreds place.

The blue box is the tens place.

The green box is the ones place.

Solution

Step 1: Write 0 in the ones place

Step 2: Multiply 4 x 5

Step 3: Write 2 in the hundreds place and 0 in the tens place

Step 4: Read all numbers below the line to get the final answer

• ### Multiply all equations.

Hints

Step one when multiplying tens is to always fill in the 0.

Write it in the ones place shown by the green box.

Next, multiply the non-zero numbers.

Solution

6 x 60 = 360

90 x 2 = 180

40 x 3 = 120

5 x 80 = 400

• ### Multiplication practice.

Hints

Rewrite the problems as shown in the image.

Write the smaller factor, which is 7 in this equation, below the larger one.

Problem number 2 has a three-digit factor of 200.

Because there are two 0s in 200, write two placeholder 0s in the final answer, as shown in the image.

Even with large numbers, follow the same steps to solve the equation.

1. Write the placeholder 0 in the ones place.
2. Multiply the non-zero numbers.
Solution
1. 7 x 80 = 560
2. 4 x 200 = 800
3. 9 x 70 = 630
4. 9 x 90 = 810
5. 8 x 60 = 480
• ### What is 3 x 30?

Hints

The first step is to fill in the placeholder, 0. This goes in the ones place.

Next, multiply 3 x 3. Write the answer in the tens place.

Solution

3 x 30 = 90

• ### Find the missing factor.

Hints

Simplify the equation by crossing out one zero from the factor and one zero from the product, as shown in the image below.

Let's look at problem number 1.

After crossing out one zero from both the known factor and product, you can find the missing factor in two ways:

1.Divide 21 (the product) by 3 (the factor).

Or

2.Count up from 0 to 21 in threes. How many times did you count up in 3s? That's the missing factor!

Solution
• 7 x 30 = 210
• 8 x 20 = 160
• 6 x 50 = 300
• 4 x 60 = 240
