Page 67 - The best we can say of the work is that it is more interesting than any novel." — Queen's Quarterly. " After having read this admirable work, I take great pleasure in recommending it to all students and teachers of mathematics. The development and progress of mathematics have been traced by a master pen. Every mathematician should procure a copy of this book. The book is written in a clear and pleasing style.", — DR.
Page vii - ... places of figures he should use in the computations, the aim being to obtain all the accuracy which the field measurements will yield without wasting time by using more significant figures than are necessary. Professor Silas W. Holman* in the preface to his "Computation Rules and Logarithms" says: — "It would probably be within safe limits to assert that one-half of the time expended in computations is wasted through the use of an excessive number of places of figures, and through failure to...

Page 2 - If several numbers are multiplied or divided, a given percentage error in any one of them will produce the same percentage error in the result.
Page 4 - ... numbers add their logarithms. Then look up the antilogarithm of their sum. The fact that numbers may be multiplied by adding their logarithms is the most basic property of logarithms. Example: Multiply 19 by 28: log 19 = 1.2788 log 28 = 1.4472 log product = 2.7260 product = antilog 2.7260 = 532 2. To divide one number by another, subtract the logarithm of the latter from that of the former. Then look up the antilogarithm of the difference. Example: Divide 532 by 28: log 532 = 2.7259 log 28 =...
