First notions of logic (preparatory to the study of geometry)

"First notions of logic (preparatory to the study of geometry)" by Augustus De Morgan is an early exploration of logical thinking designed to prepare students for geometry. This book explains the basics of logic, focusing on how to build solid arguments and draw correct conclusions. De Morgan breaks down different kinds of statements, like positive and negative ones, and how they affect our reasoning. He shows readers how to get from facts to accurate conclusions, stressing the need for definitions to be clear. Concepts like syllogisms and contradictions are presented in a way to give students the tools they need to think analytically, setting them up for success in math.
