6.022 X 1023 - 6.022 X 1022
= 5.419 X 1023
======================
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).
Scientific notation is not a problem that needs to be "solved".
The steps, in order, will depend on what you wish to do: convert from normal to scientific notation, the converse, perform one of the basic operations of arithmetic on numbers in scientific notation.
Same.
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.

Same.
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.
Yes, it does.

6 x 10-3.
When adding or subtracting numbers in scientific notation, the exponents must be the same to ensure that the terms are expressed in the same scale. Scientific notation represents numbers as a product of a coefficient and a power of ten, so if the exponents differ, the values are on different scales, making direct addition or subtraction impossible. By adjusting the numbers to have the same exponent, you can accurately combine the coefficients before simplifying the result back into proper scientific notation.
There are only two things:The exponents must be the same before subtracting, andThe mantissa for the answer must lie in the range [1, 10).
