in adding scientific notations you have to make their exponents the same then add the numbers. after you add coppy th x 10 and its exponent
ex.
1.25 x 10e10 + 7.5 x 10e9
=1.25 x 10e10 + 0.75 x10e10(you can see that the decimal point is move to the left so that its exponent will be equal)
=2.0 x 10e10(final ans.)
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.
Scientific notation is of little use for long mathematical expressions. It is used to express very large or very small numbers - not expressions.
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
20,000 + 3,400,000
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
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.

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 grammar refers to the conventions and rules for writing numbers in scientific notation, which typically expresses a number as a product of a coefficient and a power of ten. The coefficient must be a number greater than or equal to 1 and less than 10, while the exponent indicates how many places the decimal point is moved. For example, the number 5,000 can be written in scientific notation as 5.0 x 10^3. This format is widely used in scientific and mathematical contexts to simplify the representation of very large or very small numbers.
To solve equations in scientific notation, first ensure all terms are expressed in the same format. If necessary, convert numbers from standard form to scientific notation. Perform the arithmetic operations, maintaining the bases and adjusting the exponents according to the rules of exponents. Finally, convert the result back to standard form if needed.
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
