A previous message pointed out Distance^2 = Distance^2, and noted that it is showing that measurments can be used as numbers. I thought I should point out the more practical point that they are probalby expressing area, volume, etc... !@@@! = d^2 = Area !@@@@@! = d^3 = Volume !@!/!%%%! = d/t^2 = Acceleration isn't it... The '-' probably indicates the primitives of the operators . {1,2,3} shows the successors used in a addition. And {3,2,1} shows predecessors used in subtraction. But I am unable to say why -P- = (X = 1), maybe X = Y, but... I thought we agreed that { was an electron not }. And } is a new symbol. I think it is possible that it refers to the electrical charge of something. In which case they inicate the charge of a ????. But this doesn't make snese because then they are measurign the charge of their homeworld. But I guess if they fed on this kind of energy it would be a useful measurement.
