- x
_{1}is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x_{2}(default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x_{3}(default: this, our actual, physical universe) - stefanboltsemasi
- x
_{1}is the black-body Stefan-Boltzmann sigma_{SB}constant [approximately equal to: 5.670373(21)×10^{(−8)}W/(m^{2}×K^{4})], expressed in units x_{2}(default: unitless/dimensionless and equal to pi^{2 / 480}) in paradigm/system/metaphysics/universe x_{3}(default: this, our actual, physical universe)

- pisu'osoi'ai
*(comp!)* - digit/number: at least almost-all of; at least almost-certain; 100%.
- pizau'u
*(comp!)* - arbitrarily much of, arbitrarily close to 1, an arbitrarily large proper fraction/percentage of

_{1}=t_{1}[years, months, days, hours, minutes, seconds] is the date and time of event/state d_{2}=t_{2}at location d_{3}=t_{4}by date/time system x_{4} - fatysaclu
- x
_{1}(me'o) is the p-adic representation of number x_{2}in base x_{3}. - temjudri
- x
_{1}is a point on time axis, of event/state x_{2}, in system x_{3}. - vendu'a
- v
_{1}=x_{1}sells v_{2}=x_{2}to buyer v_{3}=x_{3}and includes d_{2}=x_{4}for a discounted price of (default free) v_{4}=x_{5} - bi'oi'au
*(exp!)* - digit/number: interval/range indicator for significant digits (determined by lesser endpoint).
- dei'i'u
- Attaches date and time starting with years and ending in seconds.
- gau'a
- mekso (no-more-than-4-ary) operator: Gaussian function f(x, a, b, c) = c e
^{-((x-a)}. - ju'au
- semi-mathematical binary operator: named number base operator/interpreter
- ka'o'ei
*(exp!)* - imaginary i, comma - spherical coordinates: first coordinate gives magnitude (complex modulus/radius) of the number, the second number gives the angle from the positive real axis measured counterclockwise toward the 'positive' imaginary axis (default: in the primary branch/Arg) as measured in some units (which that number should contain; the contextless default will suppose radians); the angle is not normalized.
- mi'i'au
*(exp!)* - digit/number: interval/range indicator for significant digits (determined by midpoint).
- ne'o'au
- mekso quaternary operator: polygamma function; for input X
_{1, X}, outputs the (-X_{2)}th derivative of Log(ne'o'a(X_{1, X})) with respect to X_{1}. - ne'oi
- unary operator: primorial a#
- se'au
- mathematical quinary operator; big operator: left sequence notation/converter - operator a, sequence b defined as a function on index/argument/variable/parameter c, in set d, under ordering e
- si'ei
*(exp!)* - numeric suffix: indicates that the number refers to portionality instead of cardinality
- te'i
- at a point on time axis
- xo'ei
