o the solution is precisely the same as shown inFig. 315. Pkoblem 258. To determine the piroduct o/ A X B X C, D being the unit.Eig. 316. First determine the product of A X B, as follows :—Draw two indefinite lines from d, at any angle. de = D (the unit).df=A. Join/ddh = B. Draw gh parallel to… … Problem 259. Midtiply I X IL X l^. The unit = f. The given lines in the preceding problem are drawn to thesedata, so the construction shown in Fig. 316 gives the solutionrequired. Problem 260. To determine the continued product of 2, 3, 4, etc.The unit = i. This problem is also constructed in the…
