Scientific Notation Rap

how do you write a number really big
without tiring out your hand, ya dig
say it’s a trillion that’s 1 and 12 zeros
1 million million, I aint writin that out bro
easy way to do it everyone from every nation
uses it, it’s called Scientific Notation
let’s start with a number like 110
look for the decimal, it’s at the end
move the decimal to the left a certain number of spaces
until there’s one space left, that’s two places
now you got 1.10 not done yet
add a x 10 with an exponent
exponents gonna be number of places you moved
in this case that’s gonna be two
now you got 1.10 x 102
drop off the zero, make it easier to write dude
yeah that Scientific Notation, call it SyNote
got about 100,000,000,000,000 cells in the human body
or 1.0 x 1014
sun is 92,955,807 miles away
write in SyNote, make it easier to say
find the decimal, move it to the left
that’s seven places, till there’s one left
round the decimal to 9.3 cuz it’s easier than
writing out 9.2955807
use SyNote so it doesn’t take an hour
9.3 x 107
SyNote also used for really tiny numbers
so writing them out doesn’t take the rest of the summer
virus of the common cold
is 0.00000003 meters bro
move the decimal to the right this time
8 places come on man don’t be blind
got 3.0 x 10-8
easier to write now man SyNote is great
in your computer you got a processor with
a width of 0.000000065 m, or 6.5 x 10-8
you’re using it right now
sign of the exponent easy to remember
simple rule to use beginning this September
large number sign is positive
small number sign is negative
SyNote uses x 10 with an exponent
as an easy way to rewrite is what I meant
whether big or small it’s for amounts that are extreme
check all your work, keep the math clean
population of US is 3 x 108
fraction of the world can you estimate
total is about 7 x 109 dude
first 7 divided by three is about 2
divide the exponents by subtracting
9 minus 8 is 1 is exactly
that’s how you do it to get 101
now you got 2 x 10 or 20 son
one human chromosome contains about
220,000,000 base pairs, or 2.2 x 108
an E.coli bacteria is 0.000002 m long, or 2.0 x 10-6
the distance to Mars is 78,000,000,000 m
or 7.8 x 1010
for numbers that are really large, or small
gotta use that SyNote
