Specifically this means the number of digits after the decimal determine the number of digits that can be expressed in the answer. This latter advantage has somewhat diminished with the widespread availability of calculators and computers. If the powers are not equal, then you must first convert the numbers so that they all have the same power of Would you like to merge this question into it? Second, it can treat the number as two separate numbers multiplied together, 1. It is much smaller than an ounce: This is also called the "rest-energy" of the particle.

This content was accessible as of December 29,and it was downloaded then by Andy Schmitz in an effort to preserve the availability of this book.

The number of digits shifted is then the negative exponent. A final zero or trailing zeros in the decimal portion ONLY are significant.

You multiply the 5 and the 3 to get 15, and then add the exponents. One fairly famous large number to chemists, at least is Avogadro's Number, the number of atoms or molecules in a "mole" of that substance.
