Professor X and his dog Y teach kids how to count exponentially by powers of 10 (1 10 100 1000 10000 etc. ) beginning at 1 and working all the way up to a googol (a 1 followed by 100 zeros) and beyond. Children fascinated by large numbers will be amazed how quickly they can count to really BIG numbers and they& 8217;ll also find answers to questions like & 8220;What comes after a trillion?& 8221; or & 8220;What& 8217;s the biggest number in the world?& 8221; Real-life examples provide plenty of fun facts such as how much popcorn Americans eat in one year or how many hairs are on a square inch of a person& 8217;s head. Along with the fun comes some powerful learning as this unique counting book helps kids understand our number system which is based on multiples of 10. Language: English
