The course consists of 24 lectures, each lasting approximately 30 minutes. Through these lectures, students will learn various strategies and techniques for performing mental calculations with ease.
Course Structure
The course is divided into several key topics, including:
1. Basic Principles of Mental Math: Understanding the importance of mental math and the foundational principles behind it.
2. Addition and Subtraction: Techniques for quick addition and subtraction, including methods to simplify calculations.
3. Multiplication: Strategies for multiplying numbers quickly, including the use of distributive properties and visual patterns.

Key Techniques Covered in the Course
Throughout the course, Dr. Benjamin introduces various techniques that students can employ to improve their mental math skills. Here are some of the key techniques covered:
1. Chunking
Chunking is a technique that involves breaking down complex numbers into smaller, more manageable parts. For example, to add 47 and 36, a student might break the numbers into chunks:
- 40 + 30 = 70
- 7 + 6 = 13
- 70 + 13 = 83
This method simplifies calculations and makes it easier to arrive at the correct answer.
2. The Distributive Property
The distributive property is a powerful tool that allows students to break apart numbers to make multiplication easier. For instance, to calculate 23 x 7, students can use:
- 23 = 20 + 3
- Therefore, 23 x 7 = (20 x 7) + (3 x 7) = 140 + 21 = 161
This approach not only aids in mental calculations but also deepens one’s understanding of multiplication.
3. Estimation
Estimation is a crucial skill in mental math. It allows individuals to quickly assess the reasonableness of answers. For example, when calculating 198 x 47, a student might round 198 to 200 and 47 to 50, resulting in an estimate of 10,000. This can help verify more complex calculations and provide a quick check.
4. Patterns and Tricks
Recognizing patterns can significantly reduce the time it takes to perform calculations. Dr. Benjamin shares various tricks, such as:
- Multiplying by 9: To multiply a number by 9, simply multiply it by 10 and subtract the original number. For example, 7 x 9 = 70 - 7 = 63.
- Squaring Numbers Ending in 5: To square a two-digit number ending in 5, multiply the first digit by itself plus one, and append 25. For example, 25^2 = 2 x (2+1) = 6, followed by 25, gives 625.
