40 (forty) is the natural number following 39 and preceding 41.
Despite being related to the word "four" (4), 40 is spelled "forty", and not "fourty". The reason is that etymologically (also in accents without the horse–hoarse merger), the words have different vowels, "forty" containing a contraction in the same way that "fifty" contains a contraction of "five".
Forty is an octagonal number, and as the sum of the first four pentagonal numbers, it is a pentagonal pyramidal number. Adding up some subsets of its divisors (e.g., 1, 4, 5, 10 and 20) gives 40, hence 40 is a semiperfect number.
Given 40, the Mertens function returns 0. 40 is the smallest number n with exactly 9 solutions to the equation φ(x) = n.
Forty is the number of n-queens problem solutions for n = 7.
Since 402 + 1 = 1601 is prime, 40 is a Størmer number.
40 is a repdigit in base 3 (1111) and a Harshad number in base 10.
The number 40 is significant in Jewish, Christian, Islamic, and other Middle Eastern traditions. It can represent an estimate, or many of something.
A number is a mathematical object used to count and measure. In mathematics, the definition of number has been extended over the years to include such numbers as zero, negative numbers, rational numbers, irrational numbers, and complex numbers.
Mathematical operations are certain procedures that take one or more numbers as input and produce a number as output. Unary operations take a single input number and produce a single output number. For example, the successor operation adds one to an integer, thus the successor of 4 is 5. Binary operations take two input numbers and produce a single output number. Examples of binary operations include addition, subtraction, multiplication, division, and exponentiation. The study of numerical operations is called arithmetic.
A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (telephone numbers), for ordering (serial numbers), and for codes (e.g., ISBNs).
I got a number in my pocket
Keep it in my wallet, right on my hip
When my paycheck's steady, I'm damn good and ready
I toll it up to my lip, and I go to the moon
I got my foot down on the throttle
Hands around the bottle, I think my speakers are blown
No rubber on my tire, I'm a gettin' higher
Higher than I've ever Known
And I ain't coming down
I can't remember the last time I touched the ground
You look at me like I'm gonna let you down
Hey, every time I come around
You got your finger on my button
Actin like it's nothing, bitchin' from your golden throne
You ain't no anybody, actin' high and mighty
Waitin' for me to explode, fire in the hole
Look out, down below, here I go
You're wasting time, why bother even coming 'round
add the bass ya'll....
add the trumpet ya'll...
well im five on a good day six, i got plenty of thing
need to fix a bigger chest with dimples in my face with
those i could be pushing seven to eight guitar in hand
add a point to my score no car slide me down to a four
six feet with a pair of blue eyes brings me back up to
five
chorus:
greater than less than equal too
youre making this way to mathematical the value of
personality seems to be dead. all walking around with
numbered halo's on our heads
well...
three's want four's and four's want five's eight's
think nine's have much better lives and its a
reasonable question to ask i guess its all worth doing
the math and i cant and lie to you and say this is
something i dont do but im a nother number crunching
fool whos calculators way overused
chorus:
greater than less than equal too
were making this way to mathematical the value of
personality seems to be dead. all walking around with
numbered halo's on our heads
and im thinking
just one time i wish i could have a nine she'd be hot
and she'd be mine just one time
but for every nine theres a two staring back at you
wish you would do what you wanted the nine too aye ayee
(ohhh noooo)90% of the mental judicial system is based
soley on superficial intuition to me that seems a bit
stange Only talk to people who we think we might be
kissn' that's a lot of ideas to be dismissing WE leave
it to humans to choose the criteria we can't change
doesn't make sence no doesn't make sense doesn't make
sense For the numbers to be where we are
concentrating In my minor sense i condesense in my
minor sense asymetrical interactions simply evaporating
simply evaporating
i'm a five on a good day six got plenty of things need
to fix i need a formua or some sort of plan to focus
I can't see nothin'
but a sphere
and the children are all
filled with straw.
filled with chaff.
(i'm flow? er? ing with the grains)
i fear
a dagger you
struck me
coming slightly.
whispers
i lapped milk from her
the inside of her elbows
like a cat
softly struck me.
i go out staggering, after midnight
just hopin'
the dark wind whispers down dark hallways
to me
to me I fear
well, that's just my way
of sayin'
daggers.
the salt from the inside of her wrists
weeping beams
hold up the moonlight
out in the moonlight keep me staggerin'
hold me up
sdaggerin' across a long black nothing.

Come new year's day's morning
Now what did you promise this time?
Can you remember
What accidentally slipped your mind?
No more degrading
Or humiliating stunts?
What were you saying
Before you pulled down your pants
You're so much more
Than a number on a mensroom wall
So much more
Than a scratch on a bedpost
You're so much more
Than a hole guys get off on
You could be anything at all
I am entitled
To speak my mind about what you do
I'm not patronizing,
I am merely endorsing:
Do what you want to
Not what others expect from you
You are a person
And should demand some respect
You're so much more
Than a number on a mensroom wall
So much more
Than a scratch on a bedpost
You're so much more
Than a hole guys get off on
You could be anything at all
You're so much more
Than a number on a mensroom wall
So much more
Than a scratch on a bedpost
You're so much more
Than a hole guys get off on
You could be anything at all
You're so much more
Than a number on a mensroom
You're so much more
Than a number on a mensroom
You're so much more
Than a number on a mensroom
You're so much more
