Mathematical reasoning is an important part of most competitive exams and olympiads today. In Mathematical reasoning, we are given a hypothesis and we analyse it. Some common concepts related to Mathematical Reasoning are a statement, conjunction, disjunction, inductive reasoning, deductive reasoning, simple statements, compound statements, fallacy, etc. Many times students get confused about these topics as they are quite different from what they have studied in Maths all the time. Mathematics seems like a subject that is based on formulas and theorems, but mathematical reasoning helps students become familiar with logical and critical thinking.
To help you master the concepts of Mathematical reasoning and prepare for competitive exams like JEE, NEET, and olympiads, the askIITians Maths experts have created these free revision notes. They include pointwise explanations for various mathematical reasoning concepts so that you can refer to them while solving mathematical reasoning problems. You must study these notes carefully as they will help you learn how to solve higher-order thinking questions easily.
