In arithmetic, subtraction is one of the four basic binary operations; it is the inverse of addition, meaning that if we start with any number and add any number and then subtract the same number we added, we return to the number we started with. Subtraction is denoted by a minus sign in infix notation, in contrast to the use of the plus sign for addition.
Since subtraction is not a commutative operator, the two operands are named. The traditional names for the parts of the formula
are minuend (c) − subtrahend (b) = difference (a).
Subtraction is used to model four related processes:
In mathematics, it is often useful to view or even define subtraction as a kind of addition, the addition of the additive inverse. We can view 7 − 3 = 4 as the sum of two terms: 7 and -3. This perspective allows us to apply to subtraction all of the familiar rules and nomenclature of addition. Subtraction is not associative or commutative—in fact, it is anticommutative and left-associative—but addition of signed numbers is both.
Subtraction and you're gone.
Just like that.
In seconds flat.
Reaction. I had none.
No more to add.
Gone from have to had.
June passed by so quick.
The timid talks and my lipstick.
July just wasn't enough.
In my plans it was never this rough.
Math is not my strong suit.
I don't know pi from a square root.
But I know subtraction.
Subtraction and we're gone.
And all of the trust
Has turned to dust.
Distractions, they were wrong.
No more to say.
Last look, walk away.
I read this in a book.
They said pages in one look.
But I saw just one thing.
And I knew the meaning.
Math is not my strong suit.
I don't know pi from a square root.
But I know subtraction.
You say two can care
And still not make a pair
And I say love just ain't fair.
Love is not my strong suit.
It never seems to take root.
(Lyrics: Andreas)
First generation born
A plague was created
The cure is in my mind
Solitude is all i see
Powerful nations repress feeling
Buried beneath the fear
Making you a coward
Buying your safety
Grey shadows fill your head
Stealing your last breath
Scared of the future
Prophecies of chaos
Subtraction of personality
Within the human race
You'll always beGreen castles from the past
Bleeding in sands of war
No man is immortal
History is no more
Confused leaders behind our backs
Stifling our ideas
Misunderstand signs of progress
Minds of time regress
Searching for an answer
To understand myself
do you know who you belong to
do you know love
do you know her face
how much subtraction takes place
do you know who you belong with
do you know who you belong to
do you know love
do you know her face
how much subtraction takes place
when i look at myself in the mirror
do i know you
when i look at myself in the mirror
i see you
so used to seeing you with me
in photographs and memory
i frequently see you there
when i stand in front of the mirror
alone alone
do you know who you belong with
do you know who you belong to
do you know love
do you know her face
how much subtraction takes place
you come from a woman's body
you're so close then so alone
came in a woman's body
you're so close then so alone
come from a woman's body
you're so close then so alone
you're in - in a woman's body
