Math Logic Code logo Math Logic Codebooks by Luke McLaughlin

Math and logic, explained so it finally clicks.

Two friendly self-study books that never ask you to leap over the basics. Every idea is broken into small steps, shown with worked examples, and explained with the why behind it — not just the rule. One book builds the full foundation; the other carries the same foundation straight into Python code.

The covers of Math & Logic Essentials and Math & Logic Essentials for Programming, 2026 editions by Luke McLaughlin.
Two books, one foundationStart with pure math and logic, or take the edition where every concept is bridged into runnable Python.

Built for self-study, not for a classroom.

These books were written for adults learning on their own: clear definitions, honest explanations of why each rule works, common-mistake notes, and quizzes with full answer keys.

Small stepsEvery subject is broken into building blocks, so you are never asked to skip ahead
The why“Idea behind it” pages derive each rule, so formulas stop feeling like magic
PracticeWorked examples with highlights, quizzes, and answer keys in every chapter

Math & Logic Essentials for Programming

The same complete foundation across 698 pages, with every idea bridged into Python: operator precedence, variables, booleans, conditionals, loops, functions, collections, and small programs you can run and change yourself. Ideal if your goal is to code.

From the preface: each concept is taught first, then shown as Python that readers can run and test for themselves.

Real pages from the 2026 editions.

This is how the books teach: a colourful idea page derives the why, then worked examples with highlights show the how, step by step.

Book page explaining why minus times minus is positive, with a number-line picture and a derivation.
Why minus × minus is positiveRules you memorised at school are derived, so they finally make sense.
Book page explaining why a negative power is a fraction, with the pattern written out step by step.
Why a negative power is a fractionEach “idea behind it” page walks the pattern until the rule falls out naturally.
Worked examples page with key steps highlighted in colour and handwritten-style notes.
Worked examples with highlightsKey steps are highlighted and annotated, like a patient tutor working beside you.
Logic page building a truth table for De Morgan's laws.
Logic and truth tablesFormal logic taught gently — the thinking skill behind every if-statement.
Book page showing how computers count in binary, with grouped dots and place-value columns.
How computers countThe number-bases part takes you from everyday base ten to binary — and suddenly computers make sense.
Page from the programming edition showing a math concept next to the Python code that expresses it.
From concept to PythonIn the programming edition, every idea lands as short, runnable code.
Geometry page with labelled angle diagrams and clear definitions.
Geometry with honest diagramsAngles, shapes, and proofs drawn clearly and labelled properly.
