x_{1} is the traditional/standard/classical strict total-order(ing) '<' which endows the (extended) real numbers.

This is the order by which -\infty (infty) < r < +\infty (infty) for all r in the reals, \dots < -2 < -1 < 0 < +1 < +2 < \dots, 0 < r_{1/q < r} for all r_{1, r} in the naturals such that r_{1 < r}, etc. Occasionally isomorphically intersects cleispoi and moinspoi. See also: enspoi.

_{1}(li) is the (signed) difference between the average of all elements/data of x_{2}(completely specified ordered multiset/list) and single number x_{3}(li; default: infimum of x_{2}under ordering x_{6}if such is finite), using averaging function x_{4}(default: arithmetic average), weights x_{5}(completely specified ordered multiset/list with the same cardinality/length as x_{2}; default: according to notes), and inherited ordering x_{6}(default: standard ordering on the set of reals). - cleispoi
- x
_{1}is the total-order(ing) '<' on the cardinals. - enspoi
- x
_{1}is the order(ing) which endows x_{2}((partially) ordered nonempty set or class). - moinspoi
- x
_{1}is the canonical total-order(ing) '<' on/of the ordinals.
