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
There is no true opposite of scientific notation, but the closest answer is Standard Notation.
You do not simply calculate scientific notation for nothing. You need a number for which you calculate the scientific notation.
It is simply 1.72*10^2 in scientific notation
It is: -5.034*10^2 in scientific notation
It is: 1.234*10^3 in scientific notation
Add them
20,000 + 3,400,000
Multiplying numbers in scientific notation is easier when the numbers are very, very large or very, very small. Multiplying 0.000000000385 x 0.0000000474 is a pain. Multiplying 3.85 x 10-10 x 4.74 x 10-8 is not.
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
Multiplying each factor by powers of ten
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."

Yes, it does.
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.
2000.1 in scientific notation is written as 2.0001 x 10^3. The number is expressed in scientific notation by moving the decimal point three places to the left to create a number between 1 and 10, and then multiplying by 10 raised to the appropriate power to account for the decimal shift.
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.................................
