Excerpt from The Elements of Arithmetic: In Theory and Practice We have not introduced into this book the negative quantity. An early introduction of negative number gives the unskilled teacher an opportunity to make the first lessons in algebra a mere blind manipulation of symbols. Nearly all the examples in this book are new. A few of the exercises were suggested by questions given at public examinations.
