Multiplying with Zeros Help Tip:

When multiplying factors like 3000 x 40 =, a smart way to solve this equation quickly and correctly is to first multiply the 'non-zero' digits (in this case, 3 x 4 = 12), and then count the number of zeros there are, (in this case, four). Finally, write the 12, followed by 0000. Doing this would give you the correct answer, 120,000.

Here is another example: 600 x 7000 =
6 x 7 = 42
There are five zeros in the equation.
Write 42 followed by 00000.
Final answer: 4,200,000

Here is another example: 600 x 50000 =
6 x 5 = 30
There are six zeros in the equation.
Write 30 followed by 00000. (That's thirty, followed by five more zeros.)
Final answer: 3,000,000
