THE FORUM Twenty-uae YOUR SYSTEM of solving algebra problems DECIDES YOUR GRADE in lVlathematics. l The railroad that reduces the number of unnecessary curves in its track, IIICTCHSCS IIS Cllfnlilg PONVCT. The boy who reduces the number of false trials in solving a problem, in- creases his scholarship and his grades, But the railroad needs the surveyor to lay out the new and shorter line. And the boy needs the advice of experts in mapping out an efficient system. From the Maflzcmaticr Department. Because word problems in algebra really apply the reasoning of arithmetic problems to the unknown quantity, fol- low this advice from Mr. Wilson :- In 'word' problems be certain you understand the meaning of each word and the problem as a whole, before at- tempting its solution. Think of similar problems in arithmetic in forming alge- braic equations. After you have solved the equation, remember what you have heard Mr. Crofts say about proofs 1- First get the idea clearly that a proof is to enable you to find out whether your solution is correct. Second, acquire the habit of making a rapid mental proof, particularly in all work with equations. To quote Mr. Jenkins :- Aim, in factoring, to acquire the ability to recognize the various groups and to handle them in a rapid manner. Do you know a factor when you see one? Mr. Xvitcraft says:- In reducing fractions, we cancel fuc- tors, not tvrnix. XVhy? When you come to quadratic equa- tions, be sure to gain a thorough knowl- edge of the subjectg for Miss Moser says:- More trouble arises in 2A geometry from a lack of knowledge of IA algebra than of 2B geometry. Learn quadratics and radicals thoroughly in IA if you wish success in Zlid year mathematics. L. E. Christman. for iauws From Sem: Sluarlu Who Have Pre- ceded You. Let system open the door of elficiency in your work. Jeanette and I had really thought of giving up algebra. Everything seemed so dismal for the future. Now every- thing is clear and it's all due to the plans we worked out. -lust a little care- fulness here and there and tlte whole problem became clear. You, too, can possess this clear mind, if you follow these helpful and practical suggestions for algebra problems. In order to solve an algebra problem, you must do several things: I. Read through the problem. 2. See what the unknown quantity is. 3. See what relations exist between it and other numbers. 4. Let X equal the Ist unknown. 5. Find an equation to suit the problem. No matter what kind of an algebra problem you want to solve, there is al- ways some unknown quantityg whereas, in arithmetic, you deal with all known facts, To overcome this difficulty, if it is one, First read through the problem as stated in the book, seeing what the unknown quantity is and what relations exist between it and other numbers. Since there is always some unknown quantity, let it be represented by X. Then. proceed to find an equation that will suit your problem. If you do this I am sure you will have no ditheulty in solving algebraic equations. - z 1 2-22-I I-I - ff . 5- - A 4: 4' 421.3

Arrow-heads can be picked up almost anywhere in the United States, but probably they were made only in a few places and became scat- tered through the extensive traveling of the Indian. In Ohio, are as thin as paper, and are made of Chalcedony and lava. Indian arrow-heads are of many sizes and shapes and were used for two pur- poses, hunting and lighting, The hunt- ing arrow-heads, easily distinguished by the two little notches on the sides, were fastened securely to the shaft, so that when they entered the body of the animal they could easily be pulled out and used till? ilu f.'l'nYF M... -. , Q75 1, , Ili 7' 'B H4 is again. The war arrow-heads, however, are triangular. and were fastened loosely to the shaft so that, when it was pulled out of the wound, the head remained. Several methods were used in making the arrow-heads. The most common was that of chipping one piece of Hint with another until a rough head was shaped. This, however. was not very satisfactory. Another method brought better results. A rough piece of flint or stone was heated red hot and water was the larger heads are fl dripped upon it from a found, gray and blue in 'll , straw, each drop flakiug color and made of llint xwfil 'otfa tiny piece of stone. anddtlrantnc. d'lhe-booner Mg!
