Move the decimal until there is one nonzero digit to the left of the decimal counting the spaces that you move the decimal. That number of spaces becomes the exponent of 10. The exponent is positive if the original number was greater than 10, but is negative if the original number is less than one.
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.
20,000 + 3,400,000
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.
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
In general the numeric part should be between 1 and (almost but not quite) 10.
- 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.

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

That there be only one digit to the left of the decimal point. (and that the exponent is always a whole number).
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."

The first number must be a nonzero single-digit integer. The exponent must be an integer.
Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.
