You should be fairly good at basic math. If not you will not gain much from this book.

With all the math that comes up in our lives, it's very important to have some general knowledge of doing computations in your head. A neat trick this book also teaches is how to find out the day of the week for any date in history. I'm reading through the book a second time now and really improving, it is very neat!

My kids are squaring numbers and multiplying by 11 in their heads. The math teachers are amazed. They've just started and picked up a couple of things in less than 30 min...pretty neat book.

This book is so great I bought three copies for my siblings! It is well worth reading this book. And, I promise, If you just pick up a few tips of how to do these lighting calculations it will WELL be worth the money. For beginners and even math PHDs. Anyone reading this could gain from it.

It is very understandabe how you could have gotten 5345 instead of 5445. When you multiply 495 with 11 you must be forgetting that 9 + 5 is 14 you take the 1 and add it to the 3 making it a 4. :)

I haven't bought the book yet but I looked at the preview Barnes and Noble provides and I'm actually squirming in my seat because it's so easy and incredible. Why was I never taught this in 3rd grade???!!!
