The Trachtenberg Speed System of Basic Mathematics

I have an older edition of this book, and have ordered this edition for a friend. This is an incredible book, you can learn very simple techniques in minutes, that will amaze your friends and family with the speed and ease at which you can do math. You can write the answer down without any calculations as the work is done very simply in your head. This is a book I delve into from time to time, in an effort to really acquaint myself with the techniques. The only prior math’s knowledge you need is the ability to count to 10! Would revolutionise maths if we taught this in schools!

Bought for my granddaughter

Interesting read

This is one of my favourite books ever. This is at least my third purchase of this book. My first purchase was when I was in high school, long before the internet was a gleam in the cloud's eye. I have been using their 9's method for checking computations since I was a teenager in my father's business…long before any calculators were available to the public. Yeah, I am old.

Eckenrechnen war früher ein beliebter Zeitvertreib in den Schulen. Hätte ich die Trachtenberg Mthode dort schon gekannt, hätte ich wohl nie verloren. Rechnen einfach, logisch und verdammt schnell. Alle Rechenschrtte sind logisch erklärt; gleichzeitig werden lerntipps gegeben. Eine tolle Ergänzung für JEDEN, der besser/schneller RECHNEN möchte.
