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.
Using a calculator will make it easier
You multiply the number together - using a calculator if needed.
The quickest way is to multiply the original number by 0.9
Multiply the number by itself.

If you want it completely accurate:multiply the number by itself (that is two times done)multiply that result by the number (three times done)multiply the last result by the numberrepeat step 4 until the number has been multiplied by itself 100 times (ie repeat step 3 an extra 96 times)If you want an approximation:Take the logarithm of the number (using tables/slide rule/calculator)Multiply the number found in step 1 by 100Find the anti-log of the result of step 2 (using tables/slide rule/calculator)Depending upon the number and your calculator you may get it accurately or just an approximation by using the power button of a calculator, eg 2100 could be [2][xy][1][0][0][=]
Get a calculator, divide the top number by the bottom number, multiply by 100 viola!
Just take your calculator and multiply 6 x 12.

Expressing a number to the "third power" means to multiply that number by itself three times. Multiply 329313.6 times 329313.6, and then multiply that answer by 329313.6. The resulting answer is the third power [329313.63].
The number 2 to the 5th power is 32. To find the answer to a number to a power, you need to multiply that number by itself the number of times of the number in the power. For 2 to the 5th power you would multiply 2x2x2x2x2 (2x2=4x2=8x2=16x2=32).
Multiply the number by itself.
Two choices: -- Multiply (the number) x (the percent using the percent % key). -- Multiply (the number) x (the percent), then divide the answer by 100. Either way, the claculator displays that many percent of that number.
