A Message from the Creator

Welcome! My name is Matthew Tambiah, and I’m the Creator of FastMath, a unique mental calculation system. I’m a former McKinsey consultant and I graduated with highest honors from Harvard with a Bachelor’s degree in Electrical and Computer Engineering and also earned an MBA from MIT Sloan.

Math has always come naturally to me, and I was always helping friends out with math and science courses in high school, in college at Harvard, and in business school at MIT. Over the years, I have seen first-hand that many people struggle with math. I always thought “If I were teaching math, I would teach it different!”

Well, now I’m doing that! I created FastMath to teach the way I think about math — and calculations in general — which was always very different from the way I had seen math taught in schools. I always looked for the simplest and most efficient way to solve problems, rather than taking a one-size-fits-all approach to calculations.

In FastMath resources I will teach you how to do this too! I will show you how to solve problems with the least amount of effort, and in the fastest and most efficient manner.
But, to do this, you really need to understand math and the underlying math principles, which I’ll also teach you in FastMath courses.

FastMath will show you that math doesn’t have to be intimidating and incomprehensible, but is actually a very useful tool. FastMath is not theoretical, but focuses on the practical applications for math in business, and in every-day life.

So join now to learn how FastMath can help you succeed in your job interviews.

Hone your mental calculation skills for Case Interviews with these mental calculation exercises I personally designed. As with physical training, to strengthen your mental calculation skills and keep them in peak condition, you need to train regularly — as the saying goes: “Use it or lose it…”

I used to do exercises like this before taking standardized tests like the SAT and GMAT — they will help you in Case Interviews or standardized tests like the GMAT, GR, SAT, or ACT.
