Unlock the potential of LaTeX for academic writing with this comprehensive guide by Favour Chukwuedo. Tailored for researchers, educators, and students, this guide simplifies the process of structuring theorems, lemmas, definitions, and corollaries in LaTeX documents. Ideal for scientific and mathematical papers, it offers step-by-step instructions for effectively using LaTeX environments. Enhance your documents with automatic numbering for clarity and easy referencing. Key Features: Basic Structure & Setup: Learn how to initialize the amsthm package in LaTeX, a critical step in setting up theorem-like environments. Customized Environments: Detailed walkthrough on defining and implementing custom environments for theorems, lemmas, definitions, and corollaries. Automated Numbering: Discover how to automatically number these elements, improving the organization and readability of complex documents. Practical Examples: Each section includes practical examples, showing you exactly how to apply the tags in your LaTeX projects. Usage Instructions: Theorem Environment: Start with \begin{theorem} and end with \end{theorem}. This guide explains how to place and format your theorem statements, with each subsequent theorem automatically numbered. Lemma Environment: Use \begin{lemma} and \end{lemma} for lemmas. This section covers the nuances of using lemmas in your document, ensuring each is properly numbered. Definition Environment: Definitions are neatly wrapped within \begin{definition} and \end{definition} tags, with unique numbering for each definition. Corollary Environment: Learn how to use \begin{corollary} and \end{corollary} effectively, with each corollary receiving its unique number. This LaTeX Environment Usage Guide is an essential resource for anyone looking to enhance their document's structure and presentation in LaTeX, especially in fields requiring precise and well-organized mathematical and scientific documentation.

1. LaTeX Environment Usage Guide
(Theorem, Lemma, Definition & Corollary)
Created By - Favour Chukwuedo
This guide provides instructions on how to use specific LaTeX environments for structuring
theorems, lemmas, definitions, and corollaries within your document. Each of these
environments is designed to automatically number the respective elements for easy
referencing and organization.
Basic Structure
1. Use the amsthm Package: The amsthm package is very useful for this purpose. First,
include it in your preamble:
2.Define Theorem-like Environments: Next, define each of your theorem-like
environments. Each will have its own counter.
I have already included the several environments in the document, each designated for a
specific purpose:
1. Theorem: For stating theorems.
2. Lemma: For stating lemmas, which are propositions or statements of lesser
importance that aid in proving a theorem.
3. Definition: For defining terms or concepts.
4. Corollary: For stating a corollary, which is a proposition that follows with little or no
proof required from one already proven.
How to Use Each Environment
Theorem Environment:
For every section in the document that needs to be identified as Theorem, begin with
begin{theorem} and end with end{theorem}.
Place your theorem statement between these tags.

2. Example:
N.B: Wrap the subsequent Theorems in the open and closed tags as described above and
all other Theorems will be automatically numbered.
Lemma Environment:
For every section in the document that needs to be identified as Lemma Use
begin{lemma} and end{lemma} to enclose a lemma.
Example:
N.B: Wrap the subsequent Lemma in the open and closed tags as described above and all
other Lemma will be automatically numbered.
Definition Environment:
Definitions are enclosed with begin{definition} and end{definition}.
Example:
Subsequent Definitions wrapped with the tag described above will receive a unique
number.
Corollary Environment:
Corollaries are marked using begin{corollary} and end{corollary}.
Example:
Subsequent Corollaries wrapped with the tag described above will receive a unique
number.
