Multiplying 342 by 21

To multiply 342 by 21, you can use the long multiplication method. Here's how you can do it:

1. Write down the numbers: Write 342 on top and 21 below it. 2. Multiply by the ones place: Multiply 342 by 1 (the ones place of 21) and write the result below the line. 3. Multiply by the tens place: Multiply 342 by 2 (the tens place of 21) and write the result shifted one place to the left, adding a zero at the end. 4. Add the results: Add the two results together to get the final answer.

Let's go through the steps:

1. Multiply 342 by 1: ``` 342 x 1 ------ 342 ```

2. Multiply 342 by 2 and shift one place to the left: ``` 342 x 21 ------ 342 (this is 342 multiplied by 1) 6840 (this is 342 multiplied by 2, shifted one place to the left) ```

3. Add the results: ``` 342 x 21 ------ 7182 ```

So, 342 multiplied by 21 equals 7182.

This calculation is based on the long multiplication method and the specific numbers provided.
