Notes: Scientific Notation
4. Scientific Notation: M · 10n a. M is a number between 1 and 10 b. n is an exponent
i. n is positive: multiply M by 10 n times ii. n is negative: divide M by 10 n times
Example: 340 = 3.4 · 102
M n
· means multiply

Notes: Decimal Notation Scientific Notation
c. Decimal Notation Scientific Notation i. move the decimal point to after the
first nonzero digit ii. n = the number of spaces you moved
the decimal place 1. n is + for numbers bigger
than 1 2. n is - for numbers less than 1
Example:
658,000
Example:
658,000.
Note: if no decimal point is written it automatically goes at the end (right) of the number

Example:
6.58,000.
Example:
658,000.
Notes: Decimal Notation Scientific Notation
c. Decimal Notation Scientific Notation i. move the decimal point to after the
first nonzero digit to get M ii. n = the number of spaces you moved
the decimal place 1. n is + for numbers bigger than
1 2. n is - for numbers less than 1
