The School of Numbers & Logic

Whole numbers, fractions, percentages, and estimation — the arithmetic a person uses daily, done confidently with or without a calculator.

The study of unknowns and the rules for handling them, from a single linear equation to the structures algebra grows into.

Why shapes behave as they do, and how to prove it — from congruent triangles to the trigonometry that measures the unreachable.

The mathematics of change and accumulation, followed by the harder question underneath: why the methods are entitled to work.

Reasoning honestly when certainty is unavailable — counting chances, weighing evidence, and knowing what a result does and does not show.

Sets, proofs, graphs, and formal logic — the exact, finite mathematics beneath every program and every airtight argument.

Interest, optimization, games, and models — the working mathematics behind loans, schedules, strategies, and forecasts.

Real data from first table to first model — collect it, clean it, chart it honestly, and stop short of claims it cannot support.
