Hardcover. Zustand: Good. Early Reprint. Hard cover binding, leather spine, 360 pp. A fascinating manual for teachers of mathematics - could be used for gifted students, home-schooled students, with some really "new" twists on teaching mathematics and history combined. Not only are many of the manual techniques "forgotten" - what are we ever going to do without calculators! - but the problems themselves will lead to fascinating inquiries. For example, "The tune of Yankee Doodle was composed by a doctor of the British army to ridicule the Americans in 1755; how many years to the present time?" or for the more advanced student, "Suppose a gentleman's income to be 600 guineas a year, and that he spends 25s. 6d. per day, one day with another: how much will he have at the end of the year?" or "There are 1000 men besieged in a town with provisions for 5 weeks, allowing each man 16 ounces a day. If they are reinforced by 500 more and no relif can be offered till the end of 8 weeks, how many ounces must gi given daily to each man?" or "If I buy 1000 ells Flemish of linen for £90, what must be sold for per ell English, to make £10 by the purchase?" Well worn, still very useful. Good condition.
