Scientific Notation
Standard Form
Move the decimal point the
same number of spaces as
the exponent.
Positive exponents = big numbers, so
move the decimal point to the RIGHT.
Negative Exponents = small numbers
so move the decimal point to LEFT
Fill in any empty spaces with
zeros and rewrite the number.
Scientific Notation
Standard Form
Move the decimal point so
that the number greater
than 1 but less than 10
Scientific Notation
Remove any
insignificant
zeros
Count the number of
decimal places the
decimal has “moved”
from the original
number. This will be
the exponent of 10.
If the original
number was a
small number
less than 1, the
exponent is
negative.
If the original
number was a
big number
greater than 1,
the exponent
is positive.
