## What is the Result of Multiplying 123456789 by 987654321?

Multiplying two large numbers such as 123456789 and 987654321 may seem daunting, but the process is actually quite simple. First, the numbers must be broken down into separate digits and then multiplied together to get the product. By following this process, we can determine that the result of 123456789 multiplied by 987654321 is 12193263112960579679.

The process of multiplying two large numbers together is known as long multiplication. This method is used when multiplying numbers that have more than one digit. To begin, the numbers are written out in the form of a multiplication problem with the larger number on the top and the smaller number on the bottom. The first step is to multiply the first digit of the bottom number by each digit of the top number, writing the results in a column. Then move on to the next digit of the bottom number and repeat the process until all of the digits have been multiplied.

### Breaking Down the Numbers

When multiplying two large numbers together, it is important to break them down into separate digits. For example, if we were to multiply 123456789 by 987654321, we would need to break down the numbers into 1, 2, 3, 4, 5, 6, 7, 8, and 9. Once the digits have been separated, the next step is to multiply them together.

### Multiplying the Digits Together

Once the numbers have been broken down into separate digits, we can begin multiplying them together. To start, we will multiply the first digit of the bottom number (9) by each digit of the top number (1, 2, 3, 4, 5, 6, 7, 8, and 9). The results of these multiplications should be written in columns below the digits. The next step is to multiply the second digit of the bottom number (8) by each digit of the top number and write the results in the next column. This process should be repeated until all of the digits have been multiplied together.

## Adding the Products Together

Once all of the digits have been multiplied together, the next step is to add the products together. This can be done by starting at the rightmost column and adding the numbers in that column together. The sum of the column should then be written in the column to the left and the process should be repeated until all of the columns have been added together. The final result of this addition will be the product of the two numbers multiplied together.

### Final Answer

By following the steps outlined above, we can determine that the result of 123456789 multiplied by 987654321 is 12193263112960579679. This multiplication problem can be solved using the long multiplication method, which involves breaking down the two numbers into separate digits and then multiplying them together. Once all of the digits have been multiplied together, the products should be added together to get the final result.
