KEY OF 23 · SCHEMATIC EXTENSION

The schematic 460 → 500 extension

One numerical operator, shown at two scales.

460

20 × 23

Selected schematic span

× 25/23

500

20 × 25

Extended schematic span

500 − 460 = 40

Five original units

5 × 460 = 2300

Five extended units

5 × 500 = 2500

From the modeled birth at day 460, +40 reaches day 500. The inclusive fortieth day is day 499: +39 completed days. The schematic numerical comparison preserves this distinction.

Figure 3. The Key of 23 operator extends 460 to 500, a gain of 40. Five such units give 2300 and 2500. This is a schematic numerical operation; the 40-unit extension must remain distinct from a presentation on the inclusive fortieth day, 39 completed days after birth.

Schematic Key of 23 operation: 460 multiplied by 25/23 equals 500, so the gain is 40. Five times 460 is 2300, and five times 500 is 2500. The 40-unit algebraic extension is separate from the inclusive fortieth-day presentation marker, which is 39 completed days after birth.
