Here’s a roadmap of books and university‑level courses that are great for starting and deepening your journey into proof thinking, theorems, and algorithmic thinking — from beginner to advanced.

📘 Introductory Books (Building Proof & Logic Skills)

🔹 How to Think Like a Mathematician — Kevin Houston

A gentle guide to learning mathematical language and basic proof strategies. Great for beginners transitioning to formal math.

🔹 Book of Proof — Richard Hammack

Designed specifically to teach how to read and write proofs, with lots of examples and exercises.

🔹 How to Prove It — Daniel J. Velleman

Structured proof techniques — induction, contradiction, cases — ideal for writing your own proofs.

🔹 The Art of Problem Solving / Problem-Solving Strategies — Paul Zeitz / Arthur Engel

Not just proof methods but thinking like a mathematician and tackling rich problems. (Commonly recommended on math forums listing proof books.)

📚 Other accessible choices

Mathematical Thinking: Problem‑Solving and Proofs — D’Angelo & West
How to Read and Do Proofs — Daniel Solow

These all help you learn to think like a mathematician and understand why proofs matter.

📗 Discrete Mathematics & Algorithm Foundations

These texts are standard in CS programs because they mix proofs, logic, and algorithm thinking:

🔹 Discrete Mathematics and Its Applications — Kenneth Rosen

Covers logic, proof techniques, sets, combinatorics, graph theory and more — excellent for algorithmic thinking.

🔹 Concrete Mathematics — Graham, Knuth & Patashnik

A classic blend of continuous and discrete math used in analysis of algorithms.

🔹 Courses covering discrete math & proofs

Introduction to Discrete Mathematics for Computer Science (Coursera) — includes logic, induction, recursion, invariants, and proofs connected with algorithms.
Mathematical Thinking in Computer Science (Coursera) — part of the discrete specialization; focuses on proof, logic, algorithm design, and reasoning.

📙 Algorithm & Theory Classics

Once you’re comfortable with proofs and discrete math, these books take you deeper into algorithm design and correctness:

📌 Introduction to Algorithms — Cormen, Leiserson, Rivest & Stein (a.k.a. CLRS)

The standard algorithms text; formal and proof‑oriented, with many correctness proofs.

📌 The Algorithm Design Manual — Steven Skiena

More intuitive, with lots of design patterns and problem‑solving emphasis (less formal, but great practice).

📌 Algorithms — Robert Sedgewick & Kevin Wayne

Accessible and thorough, with implementations and analysis.

📘 Advanced Theoretical Paths

If you love proofs and want to go beyond basics:

🔹 Combinatorics: The Rota Way – (Advanced text, more abstract)

A graduate level combinatorics book packed with deep theorems and proof techniques.

🔹 Formal logic & proof theory texts

Topics like sequent calculus and formal proof systems sit between math and CS and help develop deep rigor.

🎓 University & Online Courses

Here are structured paths you can take:

🧠 Proof & Logic (for beginners)

Intro to Mathematical Thinking / Proof Techniques (many universities offer these as “bridge” courses)
Discrete Mathematics (widely offered for CS majors)

📊 Algorithms & Theoretical CS

Introduction to Algorithms (often two semesters: design and analysis)
Data Structures & Algorithms (proofs of correctness and complexity)

🧪 Deeper Into Theory

Computability & Complexity (why some problems can or can’t be solved efficiently)
Proof Assistants / Formal Verification (Lean, Coq, Isabelle)

GitHub lists like awesome‑theoretical‑computer‑science collect many courses and lecture notes in math/CS theory if you want organized references.

🧠 Tips for Sequencing Your Learning

Start with proof books — Hammack, Velleman, Houston
Move into discrete math / logic — Rosen, Concrete Math
Take algorithm design seriously — CLRS, Skiena
Explore advanced theory or formal systems if you want rigor like in research
