The appearance of the inexpensive hand-held calculator in the 1970's spawned a new form of recreation. Some of the digits rendered in the display had the appearance of letters when turned upside down. For example, zero was an "O", one was an "I", three was an "E", five was an "S", seven was an "L" and eight was a "B." Problems were then invented where people inserted words into their calculators in numeric form, performed the operations and got a word back in numeric form that was translated by turning the calculator upside down. This book is a collection of such problems that conform to a biblical theme and solutions are included. It is an interesting way to study bible passages and I am sure that young children would find them amusing. My experience is in recreational math/words using a calculator and for a short time there was a great interest in the calculator word games. I personally found the problems fun to work through.
