Scientific Notation Rules
RULE #1: A number is expressed in scientific notation when it is in the
form a x 10n (where a is between 1 and 10 and n is an integer)
RULE #2: A positive exponent shows that the decimal point is shifted
that number of places to the right. A negative exponent shows that the
decimal point is shifted that number of places to the left.
Scientific Notation Rules
RULE #3: To add/subtract in scientific notation, the exponents must first
be the same. If they are different, you must move the decimal either
right or left so that they will have the same exponent. For each move of
the decimal to the right you have to add -1 to the exponent.
For each move of the decimal to the left you have to add +1 to the
exponent.
RULE #4: To multiply, find the product of the numbers, then add the
exponents.
RULE #5: To divide, find the quotient of the number and subtract the
exponents.
