Shared foundation · 12 modules
A reusable mathematical spine for science, engineering, and any discipline that needs quantities, change, uncertainty, and computation.
Every module has a stable ID, prerequisites, engineering uses, source records and a schematic visual. Engineering links to these same modules instead of copying their definitions.
Numbers become useful when their operations preserve meaning and units.
02 · 01 · quantitiesEquations describe relationships between measurable quantities.
03 · 02 · shapeShape, angle and scale connect drawings to vectors and mechanisms.
04 · 02 · shapeA graph shows how one quantity changes when another changes.
05 · 03 · changeThe derivative measures an instantaneous rate of change.
06 · 03 · changeAn integral adds small contributions into a total.
07 · 04 · many variablesEngineering fields depend on position, time and several design variables.
08 · 04 · many variablesMatrices organize coupled equations and transformations.
09 · 05 · modelsA differential equation states how a system changes rather than only its final state.
10 · 05 · modelsVariation becomes evidence only when sampling and assumptions are explicit.
11 · 06 · computationA numerical result is an algorithm, inputs, assumptions and error analysis.
12 · 06 · computationAlgorithms turn repeatable reasoning into inspectable procedures.
The modules are original Lilerno teaching structures supported by the listed sources. They do not claim academic credit, professional certification, or complete coverage of every specialist field.
