Scientific is just the simplification of longer numbers and then putting how many places you moved the decimal as the power of 10.
For example;
180000000 is the same as 1.8 x 108
The number you put the power of 10 to is also how you take it back to its longer form, you just move it that many decimal places to the right if it is a positive and to the left if it is a negative.
Another example;
0.0000000078 is the same as 7.8 x 109
Another thing. The number before the (x 10) is generally meant to be less then 10.
Answer 2:
The rules for scientific notation state that the number being times 10n must be a real number between 1 - 10. So .2 x 102 is not acceptable. 1.2 x 102 is acceptable. n must be a whole number and cannot be a decimal, fraction, or otherwise a non real number. 1.2 x 102/3 is not acceptable and 1.2 x 109898989898 is acceptable (just would be a very very very long number)
3 significant figures folowed by the 10^*
e.g.
345000 written in std notation is
3.45 X 10^5
In scientific notation the answer would be 1.8 multiplied by 109

You have safety rules in a lab, and elsewhere, so you will not hurt yourself or others.
In scientific notation all numbers are written in the form: a*10b where a is a decimal number such that 1 ≤ a < 10 and b is an integer.
I don't know what you mean "how to write the rules." In the US, "standard" notation means "long form", i.e. 6,000,000, while "scientific" notation means the exponential form, 6x106. I had thought it was the same in the UK, but Mehtamatics says otherwise: "Standard notation and scientific notation are the same in terms of UK usage of these phrases."
- when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.
Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.
If it is unambiguous and can be recognized by a computer it's probably OK. For very large or very small numbers the format is normally n.nnnnn x 10m in the form n.nnnnnEm or similar. All integers have to be written out exactly.
Scientific Notation, Standard Form and Exponential Notation are used in different countries but all have the same meaning. It is a way of expressing a number as a value between 1 and 10 multiplied by a power of 10. 5.63 x 10² is the standard form number of 563. 8.6927 x 10^4 is the standard form number of 86927.
20,000 + 3,400,000
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!

Scientific notation is a useful way of dealing with very large and very small numbers. It allows them to be presented in a form where their magnitude can be seen more easily. Also it can simplify calculations by allowing you to concentrate on the significant digits rather than the orders of magnitude which are very easily dealt with. This latter advantage has somewhat diminished with the widespread availability of calculators and computers. But previously people used log tables and slide rules for multiplication and division. These calculating devices depended on thinking of numbers in their scientific notation.
1 With addition change the scientific notation back to 'normal numbers' and then add accordingly 2 With subtraction change the scientific back to 'normal numbers' and then subtract accordingly 3 With division subtract the exponents and divide the decimals 4 With multiplication add the exponents and multiply the decimals 5 Note that if changes occur below 1 or greater than 9 in the decimal element of the scientific notation then appropriate adjustments must be made
to convert scientific notation to decimal you count the number of spaces up to the last digit then put the decimal point then put x10 to the power of if how many places you move the decimal point.................................
