In building cutting two 1metre long pieces of timber will not give a 2 metre piece unless some sort of fixing is used (for non structural uses only),

I understand mathematics abstracts to a desired unit of a dimension, in the timber case,length and it compares length units. The reason for measuring is for use and use depends on whole planks.

I propose using the + symbol attached to answer to indicate the length is a group of timbers rather than one single uniform entity. Of course, there can be work done to convert +2 or 2+ to 2, then all good with restrictions. A negative grouping is already signed because naturally nothing is self aggregating and is whole by its very presence against not negative. If units use requires, certain negative units might need something like -2-.

Summing up, at least with 10$, you know what you are going to get. +10$ not so much.

       I've successfully failed to understand this one.

       If it's any consolation, the Venn diagram for this idea has two domains, one of which contains [wjt] as its sole member, and the other which contains "everyone else".   

       We leave it to the class to label the domains.

       A shame really. The idea is crying out for a doubleplusgood comment.

       So... tolerancing?
RayfordSteele, Apr 04 2020
  

       It must be admitted that the introduction of the concept of the "negative plank" is uniquely innovative. For those presented with the problem of a plank which is slightly too long for the assigned task, rather than cutting off a portion (which is wasteful), attaching an appropriate length of negative plank is much more elegant.   

       It would also grealy simplify transport of long lengths of material. If, for example, a long length of pipe had an equal length of negative pipe attached prior to shipping, the space occupied would be proportionately reduced, and smaller vehicles could be used. After delivery, the negative pipe would be detached, and each pair of negative pipes combined to give an additional length of normal pipe.   

       It's just astonishing that this has never previously been tried.
8th of 7, Apr 04 2020
  

       Wouldn't a length of pipe and an equal length of negative pipe require no space at all?
tatterdemalion, Apr 04 2020
  

       Yes, but then it woud be too easy to lose it. Besides, try getting the bloke at Goods Inwards to sign a delivery note for a truckload of no pipe.
8th of 7, Apr 04 2020
  

       Though, the truck driver would have to show his/her boss the signature for the no pipe he/she got off the Inwards Goods guys.   

       [tatterdemalion] True, that would be a pipe length in zero space.
wjt, Apr 04 2020
  

       So if I purchase a length of negative pipe for a negative amount, the duplicate positive length comes along with it free of charge.   

       I think I'll replumb the house.
whatrock, Apr 04 2020
  

       No, no, no, NO. Sheesh, how can you be so ignorant? You can buy one length of positive (normal) pipe for the usual price, or two lengths of negative pipe for twice that price.   

       Where you save is on the shipping. You buy two positive pieces and two negative pieces The negative pieces are each joined to a positive piece for transport, thus occupying zero length (although the diameter is unchanged). On delivery you unpack the zero length pipe, separate it into positive and negative portions, and join the two negative lengths together to make a double positive length. You then have the equivalent of four lengths of pipe.   

       Please, do try to keep up.

       Simply extend this proposal to include complex numbers and it can then also deal with two-dimensional items.

       //truckload of no pipe//   

       've got a truckload of post holes; maybe you can fit it in there some how
lurch, Apr 05 2020
  

       Sounds ideal - if there are no special shipping and handling requirements, we're sure that a deal can be reached.
8th of 7, Apr 05 2020
  

       Actually, this idea made perfect sense to me. I'll go back to bed 'till I feel better.   

       (Not saying I agreed with it - if my shipment ended up containing a +1 gallon glass jug of maple syrup, when it was only intended to be 1, I'd disagree with the "+" nomenclature.)

       But you also can only saw the right side of the line once. You can only make the cut once, be it right or wrong.   

       What do you say to that, Mister Clever ? Eh ? Eh ?

pocmloc, Apr 06 2020
  

       [whatrock] Yeh, but you've forgotten delivery costs.   

       [lurch] Post holes will fit on the truck but installation is the problem. And the + tells you it's not in a jug, bring a box.   

       [ bigsleep] Aren't you opening up again the problem of an infinite varying +s on The ultimate unit 1. Working the local 1+1 => 2 seems the importance.   

       [pocmloc] I agree, blink and take a few breaths, and really look.
