Addition is a mathematical operation that represents combining collections of objects together into a larger collection. It is signified by the plus sign (+). For example, in the picture on the right, there are 3 + 2 apples—meaning three apples and two other apples—which is the same as five apples. Therefore, 3 + 2 = 5. Besides counting fruits, addition can also represent combining other physical and abstract quantities using different kinds of numbers: negative numbers, fractions, irrational numbers, vectors, decimals and more.
Addition follows several important patterns. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication. All of these rules can be proven, starting with the addition of natural numbers and generalizing up through the real numbers and beyond. General binary operations that continue these patterns are studied in abstract algebra.
Well that is what we cry
Feelings we keep inside
And you are not in the right
And you've no reason to hide
It's that we must collide
Nothing can overwrite
And you are not on my side
And we will never arrive
Be quiet at times to learn
That's /Life's about to take a turn
And I am fixing to burn
From which I'll not return
A little bit of love
From somebody above
Life is addition in any way
There's no such time now as today, today
Saw you walking back from a nightmare
Won't change what you're to do, well I don't care
I grew up there and I wasn't scared
I am from there, I was born there
Forgive me if I cry
Look when you lifted the sky
Everybody emptied their slime
Those memories stole my side
And will you sit by my side,
If me not live past tonight?
Life isn't here and so streaming
What was the feeling to stream again, stream again?
I am becoming a voyeur
I am a small man, I told ya
I don't miss coming at all
Saw you walking back from a nightmare
Won't change what you're to do, well I don't care
I grew up there and I wasn't scared
I am from there, I was born there
Well that is what we cry
Feelings we keep inside
And you are not in the right
And you've no reason to hide
That's when we must collide
Nothing can overwrite
And you are not by my side
And we will not arrive
Saw you walking back from a nightmare
Won't change what you're to do, well I don't care
I grew up there and I wasn't scared
