Lightning Fast Algorithms For The 4 Operations

Course Description:

This course is unique because it presents the ancient system of Vedic mathematics from India but in a modern context, i.e. the insights of an experienced math coach. There are no specific exams in mind, but since we are dealing with the foundation of all math, i.e. the 4 operations of addition, subtraction, multiplication and division, it inevitably will be useful in any kind of assessment.

• online tests (groups of practice examples with solutions following): 83, spread over 26 lessons

Here is an outline of the course:

Topic 1: Accelerated Addition

• Add a large group of digits by pairing or tripling them off first into tens sums, a faster method then just adding on another number.
• Use the simple method of digit sums to check whether your answer is correct or not.
• Combine left-to-right adding of columns with expanded notation for very rapid, even mental calculation
• Graduate to Vedic addition, which tackles even tougher problems with faster speed.

Topic 2: Subtraction Without Borrowing

• Use backwards addition to retrace from the smaller number back to the larger one
• Learn a pre-Vedic way to subtract left-to-right, invented by the author, that can be done mentally
• Learn the famous Vedic bar numbers - which harnesses negative numbers

Topic 3: Mental Multiplication

• Again going left to right, learn how to solve in your head for the product, using expanded notation
• Step up to Vedic multiplication, which will empower the learner to multiply two 3-digit numbers entirely in your head

Topic 4: Making Long Division Shorter

• Learn to divide horizontally, not vertically
• Learn the famous Vedic flag division for two-digit divisors, which fills a fraction of the space of Western long division
• Step up to 3 and 4-digit divisors and learn both decimal and whole number remainders in a very unique way.

Topic 5: Multiplication: Special Cases

• Learn to multiply 997 X 993 in about 6 seconds
• Extend the above skill to even more general situations
• Learn to recognize the pattern of two factors symmetrically equidistant from a "friendly" square root for rapid solving.

Topic 6: Division: Special Cases

• Learn that some divisors can divide by just adding or subtracting their digits, i.e. no division!
• Take advantage of divisors "near a base" i.e. a power of 10, for super-rapid quotients
• See division of multi-digit numbers as the reverse of multi-digit multiplication for a unique algorithm.
