Scientific Notation!

2. Scientific Notation
Shorthand way of writing very large or very small numbers
This way we can report an extreme number without fear of losing zeros!
General expression:
M x 10n
M is a number
1 ≤ M < 10
n is an integer that represents how many times you moved the decimal point to get M

3. Rules! When we do math using scientific notation, there are rules
Adding and subtracting:
All numbers that are added or subtracted must have same exponent (n number)
Multiplying:
Multiply the M value, add the exponent
Dividing:
Divide the M value, subtract the exponents
