The system by which we name numbers is one of the least understood topics.

Do you have a problem with operations?
Do you have a problem with Algebra?
Do you have a problem with Calculus?

Often it is because they don't understand the Decimal Place Value System!
Place Value cover

The concepts of numbers, and how they work, can be tricky. The Decimal Place Value System is not a trivial one! It took mathematicians many centuries to get it right, especially because the concept of Zero had to be understood well before the system could work well.

This book explains ALL of it in a simple VERY EASY way.

After less than an hour a 6 years old could name or write if told numbers in the Quadrillions

(How many know it is a number with 19-21 digits?).

Each lesson has charts to illustrate the ideas and is followed by a worksheet.

And of course, Money Back Guarantee!
