Q&A

What is the procedure for multiplying a multi-digit number by another multi-digit number?

The procedure involves breaking down the problem into a series of multiplication steps, one for each digit of the bottom number. In each step, multiply the bottom digit by each top digit and keep track of any carried digits.

What should I do if the bottom number has more than one digit?

Repeat the multiplication procedure for each digit of the bottom number separately. Each digit will have its own set of multiplication steps and a separate answer line.

How do I add the results of the separate multiplication steps together?

After completing all the multiplication steps, add the answers from each step together by starting from the ones place and carrying any digits as necessary.

What if the answer has more than one digit?

If the answer has more than one digit, leave the ones digit in the answer line and carry the tens digit to the next column.
