Scientific Notation
What is Scientific Notation?
Scientific Notation is a form of Math
that is used to express big numbers in a smaller form and small numbers in an easier way to remember. the first number has to be bigger than one but less than ten.
3.7*10
4
First look at the exponent
3.7*10
4
=
3_ _ _ _
Put the first number then add spaces
after it. To know how many spaces look at the exponent.
37000
Then add the number after the decimal to the space after the first number. Put 0s on the rest of the blank spaces

37,654=3.7654
First make the number less
than 1.
3.7654*10
4
Then put *10. After that count
how many numbers there are after the decimal.
3.5562*10
-5
Move the decimal 5 places
to the left.
0.000035562
Add zeroes in the middle.
Tip: Add one number less of 0s of the exponent.
0.0000035
First move the
decimal place to make it
greater than one.
3.5*10
-6
then count how many
places you moved it and put
is as a negative. Add the *10.
