How to Multiply Large Numbers

Preview

When I say large numbers I mean numbers like 450 and to make that even more larger lets do 450*23.
Now don't freak out, this problem may look like the hardest thing in math when this is just as simple as doing one digit multiplication! To do this you first have to write this problem vertically like this

450
x23

Now, all you have to do is follow the rule of multiplying numbers, remember you are going to multiply the smaller number by the larger number so lets first do 450x3 because we always start from the right in the smaller number and go to the left.

   450
   x  3    
1,350

Now let's do 450x20:

450
x20
9,000

Now that we have our products, just add them together to get the final answer!

   9000
 +1350
10,350

So our product to 450x23 is 10,350.
