Integers Rap

Chorus:
life aint as simple as one and one is two
gotta talk about negatives wichu
integers include the entire bunch
in Latin that means “whole” or “untouched”
whole numbers and their negatives
are all called integers kid
zero are part of integers, I aint lyin’
first ones to know this were the Mayans
was a place holder in their calendars
of a base 20 system, not 10 like ours
probably ‘cuz they didn’t just count on their hands
also on their toes in that Chiapas land
southernmost part of Mexico
round 36 B.C. wrote the first zero
by 628 had it in India
written in a book by Brahmagupta
world won’t end in 2012 so don’t be scared
starts a new baktun of bout 400 years
this ain’t no show like gigante
breakin’ it down like Jaime Escalante
start with number line in both directions, yo
positives on the right, increase as they go
negatives on the left, don’t get messed up
value becomes less as numbers go up
Chorus
to add, go right from the starting point
to subtract go left from the starting point
answer is on the number that you land
can do it another way, yes you can
adding a negative is an easy situation
change to positive while changing to subtraction
subtract a negative, gotta do the same
switch to addition and to positive you change
for example take 18+(-7)
answer you get gonna be 11
or if you take 30-(-10)
40 is your answer my friend
or try 4+(-8) know what you get
-4 will be your answer, that’s a sure bet
if you got 4 and lose 8 you down a few bro
you owe four and that’s less than zero
Chorus
multiply and divide gotta know something
couple rules now while that beat is pumpin’
signs are same answer is positive
signs are different answer is negative
a negative times a positive is a negative
a positive times a negative is a negative
a positive times a positive is a positive
a negative times a negative is a positive
divide is the same rule as multiplyin’
that’s all there is to integers, stop ya cryin’
add, subtract, multiply or divide
it’s all good man, give it a try
-9 times 4, don’t need no tricks
signs are different so you get -36
-3 times -5 gives ya +15
‘cuz signs are the same, u know what I mean
-40 divided by 8
answer is -5, aint that great
54 divided by -6 equals -9
gon’ be negative each an every time
