A propos du livre

Présentation de l'éditeur

Early ideas are not usually tme, bat need reviai Dgand revising before they are thoroughly practical. There is only one right, bnt many wrongs, only one right answer, and one right way to find it, Since thought kindles at the fire of thonght I have no apology to make for giving to the world the true science of nnmberj and how to apply it easily and accurately, for mnch time is saved, and above all tihetmecnltureand discipline of mind afforded here are above price. The alphabet is the important feature Id every soience, hence it ought to have our first and best thonght, for begin right always right, begin wrong stnmble along. Ten is the base of onr system of notation. Now let brepresent the base of any system of notation, and bdivided by bequals the zero power of b. Now to eliminate the literal terms of dividend and divisor, we divide both terms of dividend and divisor, , by b, and get the nnmerical equivalent ,one one, hence according to axiom first the zero power of the base of any system of numerical notation must be .H ence number you obeerve has two terms which I denominate the unity and unit terms of number the unity term below and the unit term above the line that divides them. Multiplying the unit term by two you get the second character in the alphabet, by three the third c., and naught the last.
