A Message From the Creator
Welcome
Hello! My name is Matthew Tambiah 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 have 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 firsthandthat many people struggle with math. I always through “if I were teaching this topic, 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 math was taught in school. I always looked for the simplest way to solve a particular problems, rather than taking a onesizefitsall approach to calculations.
In FastMath 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, which I'll also teach you in FastMath courses.
FastMath will show you that math doesn't have to be scary and incomprehensible, but is actually a very useful tool.
So join now to learn how FastMath can help you succeed in your job interviews.
