Scientific notation is just a way of writing a very small or very large number in shorthand. This form of writing number makes it easier to read and is less characters.
For example; the number 89000000000000 can also be written like 8.9 * 10^13
for smaller numbers like 0.000000000000009 can be written like 9 * 10^-15
Notice that when it is a smaller number the exponent is negative, that is because the decimal is moving to the right. When the exponent is positive, the decimal moves to the left.
Note: * means multiply.

Subtract them.
Same.
Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent
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.
Only if the numbers to be converted into scientific notation are the same otherwise the exponents can vary according to the size the numbers.

In scientific notation, you use exponents divisible by 3. For example, 12,750 is 12.75 × 10³ instead of 1.275 × 10⁴.
It is: 9.3*10^7 in scientific notation
yes its really important
Subtract them.
Yes. Here is your answer:123.4 in Scientific Notation = 1.234 x 102654.321 in Scientific Notation = 6.54321 x 102
Because scientific notation is expressed in exponents of 10 as for example 13,000,000 is 1.3*10^7 in scientific notation
4,500 can be written as 4.50 × 103 in scientific notation.
4.4 x 10^3
Same.
It is: 1.0*10^7 in scientific notation
