The axiom definitions that follow derive from the 19 axiom definitions in Axioms for Real Numbers as interpreted for Wave Numbers.
- The numbers 2?? through 10?? are defined by 2?? = 1?? + 1??, 3?? = 2?? + 1?? etc. For example:
- 2^ = 1^ + 1^
- 3^ = 2^ + 1^, etc. and
- 2v = 1v + 1v
- 3v = 2v + 1v, etc. and
- 2i^ = i^ + i^
- 3i^ = 2i^ + 1i^, etc.
- The decimal representations for other numbers are defined by the usual rules of decimal notation. For example:
- 23^ is defined to be 2*10^ + 3^
- 23v is defined to be 2*10v + 3v
- 23i^ is defined to be 2*10i^ + 3i^ etc.
- Note that the operator is a Counter in these examples.
- The additive inverse of a is –a and satisfies a + –a = 0 and whose existence and uniqueness are guaranteed by Axiom 11.
- The difference between a and b is the Opposite Value defined by = a + –b, and is said to be obtained by adding the flip of b to a.
- If a ≠ 0, the reciprocal of a in R1 and R2 is the Opposite Value a-1 that satisfies a*a-1 = 1^ where a-1 = 1^/a and whose existence and uniqueness are guaranteed by Axiom 12. The reciprocal is a multiplicative inverse in that multiplying by the reciprocal of an Opposite Value is the equivalent of dividing by the Opposite Value. Reciprocals of expressions exist, such as (4^ + 3iv)-1 = (0.16^ + 0.12i^)
- If a ≠ 0, the reciprocal of a in R3 is the Opposite Value a-1 that satisfies a*a-1 = 1‡a‡a where a-1 = (1‡a‡a/a) and whose existence and uniqueness are guaranteed by Axiom 13. The reciprocal of an Opposite Value is a not a multiplicative inverse which do not exist in R3. Reciprocals of expressions do not exist in R3.
- If b ≠ 0, the quotient of a and b, denoted by a/b, is the Opposite Value obtained by dividing a by b. For example, in R3: 5^/2jv = 2.5i^ = 5^*1/2jv = 2.5i^
- An Opposite Value is said to be rational with a rational Counter if it is equal to p/q for some integers p and q with q ≠ 0.
- An Opposite Value and its Counter are said to be irrational if the Opposite Value is not rational.
- The statement a is less than or equal to b, denoted by a ≤ b, means |a| < |b| or |a| = |b|.
- The statement a is greater than b, denoted by a > b, means |b| < |a|.
- The statement a is greater than or equal to b, denoted by a ≥ b, means |a| > |b| or |a| = |b|.
- The set of all ^ Opposite Values in a dimension is denoted by R?^, and the set of all ^ integers by Z?^.
- The set of all v Opposite Values is denoted by R?v, and the set of all integers by Z?v.
- All Opposite Values, with the exception of 0, are greater than 0.
- An Opposite Value a is said to be nonvee if a = 0 or has a ^ sign
- An Opposite Value a is said to be nonhat if a = 0 or has a v sign
- If a, b and c are distinct Opposite Values with the same Opposite Sign and Opposite Type, an Opposite Value c is said to be between a and b if either |a| < |c| < |b| or |a| > |c| > |b|.
- The square of an Opposite Value a is the Opposite Value a*a, denoted by a2.
- If S is a set of Opposite Values, an Opposite Value b is said to be the largest element of S for that Opposite Type and Sign if b is an element of S and, in addition, b ≥ x whenever x is any element of S for that Opposite Type and Sign. Thus there is a largest element of S for each Opposite Type and Sign. The term smallest element is defined similarly.
- If S is a set of Opposite Values, an Opposite Value b is said to be the largest absolute element of S if b is an element of S and, in addition, |b| ≥ |x| whenever x is any element of S. The term smallest absolute element is defined similarly.
- If S is a set of Opposite Values, an Opposite Value b (not necessarily in S) is said to be an upper bound for that Opposite Type and Sign in S if b ≥ x for every x with that Opposite Type and Sign in S. It is said to be a least upper bound for that Opposite Type and Sign in S if every other upper bound b’ for S satisfies b’ ≥ b. The terms lower bound and greatest lower bound are defined similarly.
- If S is a set of Opposite Values, an Opposite Value b (not necessarily in S) is said to be an absolute upper bound for S if |b| ≥ |x| for every x in S. It is said to be a least absolute upper bound S if every other upper bound b’ for S satisfies |b’| ≥ |b|. The terms absolute lower bound and absolute lowest bound are defined similarly.
