Transcript Scientific Notation and Order of Operations

By
Kyle Chisholm
Scientific notation is a way of writing big
numbers without actually writing them out. To
write scientific notation you write out the
numbers of the number that aren’t zero as a
decimal higher than zero but smaller than
ten,(example: 596,000,000 would be 5.96)
multiplied by 10 to the power of x.
Example: 596,000,000 would be 5.96x10⁸. You put
10 to the power of eight because it you must
move the decimal in 5.96 to the right eight
times to get the original number.

Order of operations tells you in which order to
solve a problem for example if you had 1003³x(5-2) you would think you do 100-3³ then
multiply that by 3 but really you would do
what’s in parentheses first, then do 3³, and
finally do 100 minus that. This is because order
of operations.
You do this because order of operations says
you do the operations in this order: First, you
do what’s in Parentheses. Second, you do the
exponents. Third, you do the multiplication
and division in which ever order they appear
in.(For example if it was 6x4/12 you would do
6x4 then 24/12. Or if it was 9/3x4 you would
do 9/3 then 3x4) Finally, you do addition and
subtraction in which ever order they appear in
like division and multiplication.
There are two methods for memorizing order
of operation. The first way takes the word
makes each operation into a letter and you say
it as a word: Pemdas.
The second method is like the first method
except it is an acronym instead of a word. P
being please, E being excuse, M being my, D
being dear, A being aunt, and S being Sally. So
if you put it together it is: Please excuse my
dear aunt Sally.
