1) The act of quantification observes "the amount or number of a material or immaterial thing not usually estimated by spatial measurement" where a specific phenomena is summated or derived into parts by observing "units" as a form of individuation.
2) This individuation observes a progression along a time line. So if I quantify an orange into 1 what I am observing is a specific amount directed through a timeline, where the orange exists as 1 quantity until some further act of division (the orange gets cut up or decomposes) or multiplication (further oranges are added, or grown from original orange) occurs.
3) The act of quantification, due to its dependance on change through time (as division or multiplication), observes that a number in itself is a form of linear direction through time itself.
4) Quantification, as finiteness, observes number as fundamentally a median of direction.
