1) Move the decimal until your number appears to be between 1 and 10 count the spaces that you move the decimal.
2) use the number of spaces as the exponent of 10 (the base)
3) if the original number was greater than 10, the exponent is positive, if the original number was less than 1 then the exponent is negative.
EX: 250,000 becomes 2.5 x 105
but 0.0025 becomes 2.5 x 10-3
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!
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."

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.
- 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.................................
Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.
It is 8.9*10^-5 in scientific notation
It is "(scientific notation)".
The scientific notation for 89,450 is: 8.945 × 104
This number in scientific notation is 9.8x10-5.
