"The cost of a mistake is the time required to correct it. With powerful languages and good programming environments, this cost can be greatly reduced. Programming style can then depend less on planning and more on exploration." ~ Paul Graham (1964 – ), ANSI Common Lisp, 1995.

@Lucian WolframAlpha says lim_(x->infinity) (2+2) = 4.

I'll take that as a yes.

So 2 + 2 = 4 is not universally true, because in apples, people may not believe that the second pair of apples exists?

comment Notation of exactness
My bad, that answer proved the proof for 2 + 2 = 5 false.

It appears that i misread that answer; it proves that the given proof is incorrect.

Almost never is not never. How is this correct when your answer is also correct?

In Python, 2. is 2.0. As linked, 2 + 2 = 5 here. How is that possible if those values are exact?

comment Notation of exactness
Okay, so in math "2 apples" are exactly two apples, but in other science i have to write "exactly" if it's not clear from the context? Then what about the mathematical proof that 2 + 2 = 5?

comment Why is Infinity multiplied by Zero not an easy Zero answer?
So you're saying 0 is not 0? How about "You can't limit infinity."?

comment What are some examples of notation that really improved mathematics?
When'd one use those, though? The universe is estimated to contain only 1e82 particles.
