What is 25 x 400?
10000 because 25x4= 100 so add in the other two zeros and you have 10000
How can you find the product of 4x100 using only mental math?
In your head, multiply 4 times 1, and then add on the two zeros on the end.
What is 1000000x1000000?
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.
6 multiplied by 100?
600. You just multiply 6 by 1 and add the two zeros that are in 100.
What is 1000 multiplied by 60?
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.
How do you multiply 40 x 250?
Multiply 4 times 25 to get 100 and then add the two zeros to get 10000
How do you multiply a whole number by 10 thousand?
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
What is 25 x 400?
10000 because 25x4= 100 so add in the other two zeros and you have 10000
How do you multiply a number by a power of 10?
Whatever the exponent is, add that many zeros to the end of the number being multiplied.
100 times 100?
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.
How can you use mental math to multiply 800 x5?
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
How can you find the product of 4x100 using only mental math?

What is 1000000000000000000 times 1000000000000000000?
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.

What is 6000000x47000?
The answer is 282000000000. You can either just multiply 6 by 47 and then add on six zeros.
Do you add the 0 when multiply decimal?
You don't. .3 * .4 = .12 No added zeros.
How many zero add to seventy crores?
Adding zeros is not a solution. No matter how many zeros you add, the answer will still be zero.
