2-hour No-Zero Multiplication
and Division Workshop
Learn how to mentally multiply and divide large numbers WITHOUT counting zeroes!
Your Instructor
I'm Matthew Tambiah, the creator of FastMath.
Over a decade ago, I began teaching a simpler, more efficient, and more effective approach to mental math and quantitative problem solving for candidates preparing for interviews at leading consulting firms like McKinsey, BCG, and Bain — collectively, these methods and material are known as FastMath
In the last decade, over 100,000 MBA, PhD, and undergrad students from leading MBA programs and universities around the world like Harvard, Wharton, MIT, Columbia, Stanford, Oxford, Cambridge and London Business school have learned FastMath methods through my in-person workshops and online courses. These students have used FastMath methods to land jobs at firms like McKinsey, BCG, Bain, Google, Amazon, Facebook, Goldman Sachs, Morgan Stanley and many other elite firms.
FastMath students have said that FastMath completely transformed how they think about mental math and quantitative problem solving in general, unlocked their full potential, and opened doors that they previously thought were closed to them.
I look forward to helping you become a Fast Calculator!
2-Hour No-Zero Multiplication and Division
Workshop Overview
This 2-hour Workshop will teach you what I think is the most important mental math skill for business: the ability to multiply and divide large numbers purely mentally, and without counting zeroes!
You can learn this in under two hours!
This course teaches methods called No-Zero Multiplication and Division. I began teaching this method over a decade ago in my workshops at Wharton and other schools and in FastMath online courses.
Today, No-Zero Multiplication and Division is taught by leading consulting firms like McKinsey, BCG, and Bain to their consultants. Furthermore, consulting clubs at leading MBA programs and universities like Harvard Business School, Wharton, and Stanford teach No-Zero Multiplication and Division to their members as well.
Course Materials
I used to teach No-Zero Multiplication and Division as part of my in-person workshops and high-end online courses. But I’ve decided to teach the basic method for free (see the Preview Video).
In this 90-Minute workshop, I will teach you how to learn No-Zero Multiplication and Division so that you can apply it automatically, without thinking about it, and do calculations with large numbers mentally without counting zeroes.
This course provides practice exercise and a mnemonic for learning No-Zero Multiplication and Division, and contains numerous Calculation Drills that you can download and print out, along with detailed Solutions, and many mental math exercises that I personally designed, so that you can master No-Zero Multiplication and Division. The course also has interactive online Calculation Drills as well.
After spending just 2 hours with the course material, you’ll be able to multiply and divide large numbers mentally, or with pen and paper, without counting zeroes!
This will completely change how you think about numerical calculation and quantitative problem solving, and is the first step in becoming a Fast Calculator!
I’ll also give you a language for mental calculations and thinking about large numbers, and my FastMath Style Guide for reading, writing, and speaking (saying) large numbers in many different contexts.
If you want to improve your mental math for business, you should definitely enroll in this course.
In ten years, I expect that No-Zero Multiplication and Division will be taught in every major business school and company, and even some high schools. You can get a preview with this course through the free video.

The course provides a detailed explanation of the No-Zero Multiplication and Division methods along with a rigorous mathematical proof. The course provides practice exercises and a mnemonic to facilitate learning No-Zero Multiplication and Division.
The course uses videos and documents, consisting of text and images, to teach the No-Zero Multiplication and Division methods and includes numerous downloadable Calculation Drills that you can print and solve with pen and paper out along with detailed Solutions and as well as interactive online Calculation Drills.
These Calculation Drills begin with simple problems and gradually progress to more complex calculations so that you can fully master the methods with steady progression and practice without being overwhelmed. I personally deigned these Calculation Drills and have tested them with many people — they are simple and highly effective.
3) How long will I have access to the course?
You will have access to the course for 12 months.
4) How long does No-Zero Multiplication and Division take to learn?
Most people can learn the No-Zero Multiplication and Division in less than 2 hours.
If you need more time, you will have access to the course for 12 months. Having access for a full year allows you to refresh your knowledge and practice as much as you want over the course of a year.
For most people, 1.5 – 2 hours of learning and practice should be enough time to master No-Zero multiplication and Division.
5) What math do I need to know to take this course?
Very little!
No-Zero Multiplication and Division are extremely simple.
You just need to know your single-digit multiplication tables, how to multiply numbers by 10, and the definition of exponents: 10^2 = 10 × 10 = 100.
That's it!
6) Do I need any other books or courses to take this course?
No, you don’t need any other books, courses, or knowledge to take this course. Just the basic math that is listed above.
7) What is FastMath
FastMath is an approach to teaching mental math, numerical calculation, and quantitative problem solving that is simpler, more intuitive, and ultimately more efficient approach to mental math and numerical calculation, when compared to “traditional math” educational resources and teaching methods, and which have an emphasis on practical business applications.
FastMath includes numerical
mental math methods that simplify numerical calculation (including
No-Zero Multiplication and Division) but is so much more than “mental
math.” Ultimately,
FastMath will teach you how to analyze and solve quantitative problems in the most efficient and intuitive manner.
8) Did you really invent No-Zero Multiplication and Division?
TLDR: Yes, I believe I did.
I began teaching No-Zero Multiplication and Division in 2013 at a workshop at Wharton and in FastMath
online courses that launched globally in 2013. I believe that I was the
first person to explain No-Zero Multiplication and Division using the
Unit Abbreviations
K, M, B, and T
by writing formal mathematical definitions of each of these
Abbreviations and providing the Unit multiplication facts which allow
one to directly multiply Units using the
Unit Abbreviations (M × K = B).
So yes, I believe that in invented No-Zero Multiplication and Division.
If you are aware of any resources that formally taught this
before 2013, please let me know. This would include explicitly defining
each Abbreviation and explicitly writing out the multiplication facts
using the Unit Abbreviations.
9) Why should I learn No-Zero Multiplication and Division?
Learning No-Zero Multiplication and Division will allow you to perform mental calculations with large numbers that most (nearly all) people cannot do without using a calculator or spreadsheet, which is a very valuable skill in business. These skills are also very valuable in business job interviews at management consulting, finance, and technology firms.
If you feel like you can mentally multiply and divide number sin the Millions and Billions just fine, or can do this with pen and paper for your job interviews, then there’s no need to take this course.
10) Why should I learn No-Zero Multiplication from FastMath?
I believe that in invented No-Zero Multiplication and Division. This courses teaches you the specific mental math exercises and Calculation Drills that I used to fully master No-Zero Multiplication and Division.
In addition, most people say that FastMath is the best (and the first) mental math course for Business Calculation. I believe I invented many of the mental math methods used in Business Calculation (such as No-Zero multiplication) and have developed the best curriculum and will continue to develop new material. So by learning FastMath, you'll prepare yourself to learn from the best Business Calculation resource available. In particular, McKinsey recruiters recommend
FastMath
to candidates who want to improve their quantitative skills for their
interviews with McKinsey. fits tI believe that in invented No-Zero
Multiplication and Division.
11) What is the course refund policy?
Our refund policy varies by course. Since this course provides practice problems for No-Zero multiplication, and the No-Zero multiplication method is publicly available on the FastMath YouTube channel, this course does not have a refund policy.
If you want to practice the No-Zero Multiplication method or learn No-Zero Multiplication, then you will benefit from this course. If you already understand No-Zero multiplication and Division, then you likely will not benefit from this course.
