You add one more zero to the end of the number

You add as many zeros to the number as you have in the power of 10.

-- Ignore the decimal point; just multiply the two whole numbers. -- After the multiplication is done, put the decimal point back into the product. Put it in the right place so that the product has as many digits after the point as the original decimal had. If there aren't enough digits in the product to do that, add some zeros to the left end of it.

Adding zeros is not a solution. No matter how many zeros you add, the answer will still be zero.

There are six zeros in a million, so you would just need to add six zeros to 15 to get 15,000,000. You can also move the decimal point over six places to the right to get the same answer.

In your head, multiply 4 times 1, and then add on the two zeros on the end.

You add one more zero to the end of the number

its very simple just add the zeros that you need

the answer is 480,000. Because both numbers have two zeros you can cancel out the zeros and add them later. So now you are left with 6×8. If you take six and add it to itself eight times, you get 48. Now we can deal with the zeros. Because we dropped 2 zeros from 600 and 2 zeros from 800 you get a total of 4 dropped zeros. You can take these zeros and add them onto 48. Adding 1 zero gets you 480. 2 zeros, 4,800. 3 zeros, 48,000. And finally 4 zeros, 480,000!! You can check your work by dividing 480,000 by 6 OR 8. If you divide by 6 your answer should be 8, and if you divide by 8 your answer should be 6.

A million times a million is a trillion, or 1,000,000,000,000. In this particular case, the shortcut is to add your zeros. When you multiply a number with 6 zeros with another number with 6 zeros, it will always have 12 zeros. In other similar problems beginning with numbers other than 1 or with more than one starting digit that is not a zero, you can just multiply the non-zero part at the beginning and then add the zeros from both multiplicands onto the end of the product, thus 60 x 200 would be 12,000. That is, you multiply the 6 and the 2 and add on the 3 zeros.

Whenever you want to multiply a number by 1000, you add three zeros onto the number. Therefore, your product would be 1203459687000.
