If you look at WikiHow you can see the following steps for carrying out long multiplication.
Step 1Follow this example. Say that you want to multiply 756 and 32. These problems don't look tough, just try to take it one step at a time. (Note that there is nothing special about these numbers - they are used for demonstration purposes on this how-to). This technique will work for any numbers, however long. Write it out like this:
Step 2Start from the right. Multiply all the numbers on the top row by 2. Six times 2 is 12, so write the units figure under the units, and carry the 1:
Step 3Now multiply the 5 and the 2, which makes 10. Also add on the 1 that is carried from the last stage. This makes 11, so write 1 on the line, and carry the other 1:
Step 4Multiply seven times the 2. This makes 14. Add on the carried 1, so it makes 15. Don't carry the tens over this time, as there are no more numbers to multiply on this row. Just write the 15 on the line:
Step 5Move to multiplying the tens now that you've done the units for the number 32. Put a zero in the units column:
Step 6Multiply six times 3. This makes 18. Again, put the 8 on the line, and carry the 1:
Step 7Multiply 5 times the 3. This makes 15 but you must add on the carried 1, so it equals 16. Write the 6 on the line, and carry the 1:
Step 8Multiply 7 times the 3. This makes 21, plus the carried 1 makes 22. You don't need to carry the 2, as there are no more numbers to multiply on this line:
Step 9Begin adding up. Now you're done with multiplying; you just need to add together 1512 and 22680. Write a plus sign to remind you of this:
Step 10Add two plus zero. This makes 2. Write that in the units column:
Step 11Add one plus 8. This makes 9. Write that in too:
Step 12Add five plus 6. This makes 11. Write the 1 on the line, and carry the 1:
Step 13Add one plus 2. Include the carried 1 to make 4. Write that down:
Step 14Add the final numbers. 2 plus nothing makes 2; write that in:
Good luck with Long Multiplication and your childs education.
