Multiply 4 times 25 to get 100 and then add the two zeros to get 10000

add 5 zeros. 1*10000 put a 1 in front and throw 5 zeros on the end. as a general rule any number that ends in zeros, you cann multiply the non zero numbers and add the total number of zeros on the end. 30*20 multiply 3 and 2, get 6 then take the two zeros (one from 30 and one from 20) get 600

10000add the zeros together

10000 because 25x4= 100 so add in the other two zeros and you have 10000

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.

Whatever the exponent is, add that many zeros to the end of the number being multiplied.

yes you can just multiply the 8 and the 5 then add all the zeros you have in the 800 to your answer. EX. 8x5=45 <-- your answer then add the 2 zeros your final answer is 4500

If I counted the zeros correctly being 18 zeros then 1,000,000,000,000,000,000 times 1,000,000,000,000,000,000 would equal to: 1,000,000,000,000,000,000,000,000,000,000,000,000 This is actually quite simple to multiply. All you do is carry a one down and add the zeros together. The total zeros is how many zeros follow the one in the answer.

The answer is 282000000000. You can either just multiply 6 by 47 and then add on six zeros.

1000 x 5,559 = 5,559,000 Anytime you multiply by 10,100,1000 etc. just add the number of zeros onto the number you are multiplying. 1000 has 3 zeros, so we will add those 3 zeros to the end of 5,559 to get 5,559,000

Apart from using a calculator, specifically if you multiply a whole number by a power of 10:* To multiply a whole number by 10, add a zero to the whole number. * To multiply a whole number by 100, add two zeros to the whole number. * Etc.

You add one more zero to the end of the number

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

There are a thousand grams in a kg. Therefore multiply 13200 kg by 1000 or add three zeros to the number =13,200,000 grams.

Just multiply 16 by 2 which is 32 and add 3 zeros. a ton is 2,000 pounds. So 32,000 pounds

You don't. .3 * .4 = .12 No added zeros.

600. You just multiply 6 by 1 and add the two zeros that are in 100.

You add two zeros at the end of the answer 80*90=7200

When multiplying with zeros you just remove the zeros and multiply the other digits then add the amount of zeros you removed to the answer. 30 x 20 = 3x2 =6 then add two decimal to the right with zeros. 600 30 x 20 = 600

60,000 An easy way to find this is to simply add 3 zeros to 60 since 1000 is a a power of ten. If you want to multiply 60 by .1 you would just take away a zero and get 6, or if you wanted to multiply 60 by 10 you would add 1 zero to get 600, or if you wanted to multiply 60 by 100 you would add 2 zeros to get 6000, and so on.

multiply the one and the three 3x1=3....then add the zeros. 300000000000000 is the answer. your either really young, or bored.

just add 2 zeros to the end of the number when you multiply and number by 100 so the answer is 13445200

Uncountable

To multiply 30,000,000,000 by 100 you simply add an extra two zeros to the end of the number, making it 3000,000,000,000

To multiply whole number by 100 simply add two zeros to the right end. Example: 341 times 100 is 34100.
