Ep 6. Mental Math and Paper

In the sixth episode of Secrets of Mental Math season 1, entitled Mental Math and Paper, the focus is on the relationship between mental math and writing down equations. The episode features Arthur Benjamin, a renowned math professor, demonstrating how to use paper and pencils to help enhance mental math abilities.

The episode begins with a discussion on how writing down equations can assist with mental math. Arthur Benjamin explains that by breaking down complex problems into smaller parts, it becomes easier to solve them. Writing down equations can help to facilitate this process.

Arthur Benjamin then goes on to demonstrate how to use a technique called "lattice multiplication." This technique involves breaking down multiplication equations into smaller parts and using a grid-like structure to help solve them. He shows how to use this method to solve complex multiplication problems in a matter of seconds.

Next, Arthur Benjamin demonstrates how to use paper and pencil to solve long division problems quickly and accurately. He explains that by breaking down the problem into smaller parts, and using a method called "chunking," it becomes much easier to solve.

The episode then moves on to a discussion about how to use paper and pencil to solve problems involving percentages. Arthur Benjamin shows how to quickly calculate percentages using a method called "proportional reasoning." This method involves breaking down a problem into simpler parts and using ratio and proportion to solve it.

The episode also features a section on how to use paper and pencil to solve problems involving algebraic equations. Arthur Benjamin explains that by using substitution and simplification, complex algebraic equations can be broken down into simpler parts, making them easier to solve.

Throughout the episode, Arthur Benjamin also gives tips on how to correctly use paper and pencil to enhance mental math abilities. He emphasizes the importance of writing down each step and taking a moment to think before proceeding to the next step.

Overall, Mental Math and Paper is an informative and practical episode that provides useful tips on how to use paper and pencil to enhance mental math abilities. Whether you are a student looking to improve your math skills or simply interested in learning new techniques, this episode is sure to provide valuable insights and tips.
