N+/-(a number)

Please pardon my ignorance but what does N+/- (a number) mean? I've wracked my pea-brain trying to figure it out.
Thanks
Jon

N = the number of bikes currently in your stable
+x = adding to the stable by x number of bikes
-x = subtracting from the stable by x number of bikes

The N+1 phrase is generally used when someone is unsure whether to keep a bike or replace it with another and has the connotation that having one more (or more variety) is better.

currently planning on replacing two with one, so that would be n-2+1

i wonder what that number is on average? My wife has slowly come around to accept the completely rational logic behind me needing a 7th bike.

I like s-1 as it captures the universe of possible nasty outcomes beyond a mere divorce.

There is another, third, rarely used equation in this system to be balanced: s+1

Buy s another bike, s increments by one; ergo, s-1 also increments by one.

N-1 is not a mathematical equation that could exist. It is like saying I am going to douse myself in hydrochloric acid to get some dirt on my face. It doesn't work that way it would just kill you. I can understand replacing one so doing like an n-1+1 because then it is just a zero transaction and that is cool.

Thanks all. Got it. I only have one with no plans to add or subtract any. So I guess I have N1 bikes?

Conventionally, the limits on a summation go from i to N.



N+1 denotes the next item in the series.

You're wrong-- N-1 is a transient, unstable state that occurs when a person gets rid of 1 bike to make room for the 2 new bikes he/she is getting the next day, a mere waystation on the path to N+1, the only truly stable state.

Fair enough. I can dig that idea.

With Rowan and me it's always N+2 ... because we each have to get a bicycle.

Copy that, although in my case it is those ice cream drumsticks. My equation is (N+1) ≤ (Sum N+1 Storage space).

This has always puzzled me.

The number of bikes you should own is N+1. To prevent separation from the spouse or whatever, it is S-1.

So,

N+1 = S -1

solve for S:

S = N + 2

I think this means one should buy two more bikes.

If I may add...at work, where my desk chair wore out the carpet, there are Rocket Scientists who all ride recumbents. So, I double checked the math, I too am confident from an orthogonal subspace perspective, it checks out.
