What is exponential notation
it's another word for scientific notation. It's "A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. The scientific notation of 10,492, for example, is 1.0492 ¡Á 104."
oops, not 1.0492 * 104, but 1.0492 * 10^4

How do you add and subtract Numbers in scientific Notation?
Exponential notation, also known as scientific notation, is a way of expressing numbers that are very large or very small in a condensed form. It involves writing a number as the product of two components: a coefficient and a power of 10.
In exponential notation, the coefficient is always a number between 1 and 10. The power of 10 represents how many times the coefficient should be multiplied by 10.
To convert a number into exponential notation, follow these steps:
1. Identify the coefficient: Find the nonzero digits in the original number and place them in a decimal form between 1 and 10. For example, in the number 567, the coefficient would be 5.67 since moving the decimal point two places to the left gives us 5.67.
2. Determine the power of 10: Count the number of places you moved the decimal point to achieve the coefficient. If you moved it to the left, the power of 10 is positive; if you moved it to the right, the power of 10 is negative. For example, if you moved the decimal point two places to the left, the power of 10 is +2.
3. Combine the coefficient and the power of 10: Write the coefficient, followed by "x 10", and then the power of 10. For our example, the number 567 in exponential notation would be written as 5.67 x 10^2.
Exponential notation allows us to express very large or very small numbers in a more concise and manageable form, making calculations and comparisons easier.
