The Dual Nature of Numbers: Cardinality & Ordinality

The Impact of Number

Language

Our Myopia with the Decimal System

Counting, an ordinal concept, dominates our early focus with numbers.

The patterns in our number words are

cognitively inconsistent with

our minds’ number sense.

Our myopia with base ten interferes with the discovery of place shapes and

subQuan meta patterns required for formula derivation and algebraic

manipulations.

The subQuan four three one two is composed of: 4 Cubes, 3 Squares, 1 Seg, and 2 Ones

Cognitive engineering perspective

H O W M A N Y ?

Each Place Value also shows Shape. The best part is that it works in ALL bases, not just base ten.

Place Shape!

If we verbalize the subQuan Algebraically: 4 ten Cubes, 3 ten Squares, 1 ten Seg, and 2 Ones

Great. We have a foundation based on

Place Shapes.

What can one build on place shapes?
