Suppose you have two numbers in scientific notation.
· Rename them so that the exponents (powers of 10) are the same,
· add the two mantissae to form the new mantissa, and append the 10 and exponent,
· if the resulting mantissa is 10 or greater then rename the mantissa and adjust the exponent accordingly.
For the first stage you may rename both numbers or either one.
For example,
3.5*10^3 + 4.5*10^4 = 3.5*10^3 + 45*10^3 = (3.5+45)*10^3 = 48.5*10^3 = 4.85*10^4
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
you take the last digit in the first one and add/subtract it to the last digit in the second one and that is your answer
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."

Same.
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.
Well, adding x10 is scientific notation. Example:456-4.56x102. this is because there are two numbers before the decimal. another example:14945-1.4945x104. if you do not get it, I'm sorry. This is the best i can explain
Yes, it does.
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.................................
