Publisher's Synopsis
Excerpt from New System of Addition: Comprising a New and Novel Method of Making All Arithmetical Calculations, Revolutionizing the Old Methods in the Fundamental Rules of Addition, Subtraction, Multiplication, and Division; Enabling Any Bookkeeper, Clerk, or Student of Average Ability to Be
The object of this work is to place in the hands of all persons, young and old, who make use of figures, information and instruction which will give them the highest speed, accuracy, and ease in their work.
It explains in language and illustrations so plain as to be understood easily by any one the methods by which "Lightning Calculators" do their work.
The "New System" will be found, on investigation, certainly no more difficult than the questions and problems submitted to youthful minds in the school-room in the ordinary arithmetics.
This work is the result of eighteen years' practical experience in actual business calculations. The author found that what his friends were pleased to call a "gift of nature," which enabled him to read columns of figures at sight, was only a killful use of ordinary faculties and laws to which he was driven by the necessities of his work. He found, upon analysis, that the principles upon which lightning calculations are made are easy to understand and to apply.
A knowledge of the System may be acquired with much less study than is required to master the ordinary arithmetics in general use.
