Scientific Notation• Used for very large or very small numbers,
eliminates the need for writing a lot of zeroes.• Example 7,532,000,000 is written as
7.532 109
• Must have a number from 1 to 9 left of decimal, all remaining numbers are to the right.
• The exponent tells how many places the decimal is moved.
• Positive exponent means decimal was moved to the left, negative exponent decimal was moved to the right.
