    Not a math for dummies book

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

    Answer to the help post

    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. :)
