Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!

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."
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.

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.
You must convert to the same exponent. Example: 2 million + 300 million, written in normalized scientific notation, is 2 x 106 + 3 x 108. You must convert to the same exponent (for example, 8), to obtain 0.02 x 106 + 3 x 108. This you can add: 0.02 + 3 = 3.02, so the result is 3.02 x 108.

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.................................

- 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.
You must convert to the same exponent. Example: 2 million + 300 million, written in normalized scientific notation, is 2 x 106 + 3 x 108. You must convert to the same exponent (for example, 8), to obtain 0.02 x 106 + 3 x 108. This you can add: 0.02 + 3 = 3.02, so the result is 3.02 x 108.
Under today's rules the given Roman numerals are equivalent to 1913
Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.
To convert a number to scientific notation, move the decimal point right or left to make the number greater than or equal to one but less than ten, and record the number of positions moved as a power of 10 - the exponent. That is, if the decimal point moves to the left by n positions, then the exponent is 10n. If the decimal point moved to the right by npositions, the exponent is 10-n (note the minus symbol).For instance, the number 123,456,000,000 is larger than 10, so we move the decimal point 11 positions to the left to get 1.23456, which is greater than or equal to one, but less than ten. Since we moved the decimal point to the left by 11 positions, the exponent is 1011 (ten raised to the eleventh power, which is 100,000,000,000) so the scientific notation for 123,456,000,000 becomes 1.23456x1011.If the original number were 0.000000123456, we need to move the decimal point to the right by seven positions to get 1.23456 (greater than or equal to one but less than ten). The exponent is therefore 10-7, thus the scientific notation for 0.000000123456 is 1.23456x10-7.To convert from scientific notation to standard notation, we simply reverse the process. If the exponent is a positive power of 10, we multiply by the exponent. Thus 1.23456x1011 is 1.23456 x 100,000,000,000 which is 123,456,000,00. If the exponent is a negative power of 10, we divide by the exponent. Thus 1.23456x10-7 is 1.23456 / 10,000,000 which is 0.000000123456.Note that scientific notation is only useful when you are not interested in the least significant portion of a number. For instance, a value such as 123,456,789,123,456,789,123,456,789 is better notated in full if you want the highest degree of accuracy. Scientific notation is generally only used to make the notation of an extremely large (or extremely small) number more concise. So 123,456,789,123,456,789,123,456,789 might be reduced to a more concise form such as 1.23456789x1026. This then equates to 123,456,790,000,000,000,000,000,000 in standard notation, which is clearly not the same value we started out with. In other words, the degree of accuracy is determined by the number of decimal places you retain in the scientific notation.
Negative numbers cannot be written in exponential notation. The rules require the number to be between 1.0-9.9.
