Multiplying Large Numbers
A Shortcut for Multiplying Large Numbers
Read on to learn an easy way to find the product of
large numbers.
PROCEDURE: To find the product of large numbers, remove the zeros at the end
of one or both numbers. Next, multiply the nonzero numbers. Finally, at the
end of the product, replace the same number of zeros that you removed from
your multipliers.
SAMPLE PROBLEM: Multiply 80,000 by 50.
Step 1: Remove the zeros from the end of your numbers, and multiply the
nonzero numbers.
Step 2: At the end of your product, replace the total number of zeros you
removed from the multipliers. Because you removed a total of five
zeros from your multipliers, place five zeros after your product.
80,000 Ã— 50 = 4,000,000
