formal is just study of logic with purely formal content and material is the branch of logic that focuses the content of reasoning.
Formal logic is logic used to examine the form that an argument is presented in. Formal logic looks at the grammar and sentence structure of an argument through a logical approach.
Mathematical logic is a branch of mathematics which brings together formal logic and mathematics. Mathematical logic entails formal systems for defining the basics and then using the deductive power of logic to develop a system of formal proofs.
OK.
Examples of formal logic include propositional logic, predicate logic, modal logic, and temporal logic. These systems use symbols and rules to represent and manipulate logical relationships between statements. Formal logic is used in mathematics, computer science, philosophy, and other fields to reason rigorously and draw valid conclusions.
Logic is a philisophy subject. It is the science and art of correct thinking. It is a science that stands for a systemized body of truths acquired through observation and experimentation. It is a systemized body of logical truths and principles governing correct thinking. It is also an art, a "techne", that teaches how to make good arguments. It weighs whether reasoning is correct or incorrect; this is the core of the problem confronting logic.
Aristotle is considered the father of formal logic. He developed the syllogism, a form of deductive reasoning that consists of a major premise, a minor premise, and a conclusion. Aristotle's work on logic laid the foundation for the study of reasoning and argumentation.
Some recommended books on formal logic for beginners include "Introduction to Logic" by Irving M. Copi, "Logic: A Very Short Introduction" by Graham Priest, and "The Logic Book" by Merrie Bergmann.

Formal logic concerns itself primarily to the correctnes rather than than the truth of a logical process. Material logic on the other hand is the truth of a material content.
No, logic and formal proof have been integral parts of mathematics for thousands of years. The ancient Greeks, such as Euclid and Pythagoras, were known for their use of logical reasoning and formal proofs. However, the development of formal logic as a field of study did occur more recently in the 19th and 20th centuries.
One highly recommended logic textbook for studying formal reasoning and critical thinking skills is "Introduction to Logic" by Irving M. Copi.
