6. Introduction to Mathematical Thinking (Coursera)

Learn to think like a mathematician, a complex cognitive mechanism that has developed over thousands of years.
Mathematical reasoning is not the same as doing math, at least not in the way it is taught in our educational system. In school math, learning procedures to solve highly stereotyped problems is a common subject. Professional mathematicians have a particular way of thinking to solve real-world problems, whether they come from the real world, science, or mathematics itself. Success in school math necessitates the ability to think outside the box. The ability to think outside the box, on the other hand, is a core characteristic of mathematical thought, and it is a valuable skill in today’s world. This course will help you cultivate a strategic attitude.

What You Will Learn –

  • Analysis of language, putting into place the linguistic apparatus.
  •  The branch of mathematics known as Number Theory.
  •  The parts of language we are focusing on have particular importance in mathematics.

Skills-

  • Number Theory
  • Real Analysis
  • Mathematical Logic

10. Probability – The Science of Uncertainty and Data(Via Edx)

Accidents, hurricanes, rogue financial markets, and obnoxious communications are all too common in the world. In addition, the planet is awash in data. Probabilistic modeling and the related field of statistical inference are important for analyzing data and making scientifically sound predictions.
Probabilistic models use mathematical vocabulary.

Moreover, although there are various and obvious applications, we emphasize the widely applicable basic principles and methodologies.

What You Will Learn –

  • The basic structure and elements of probabilistic models.
  • Random variables, their distributions, means, and variances.
  • Probabilistic calculations.
  • Inference methods.
  • Laws of large numbers and their applications.
  • Random processes.

Skills –

  • Number Theory
  • Real Analysis
  • Mathematical Logic
  • Language

Pre-requirements –
