OLD NUMERAL SYMBOLS

15

½, ⅓, ⅔, ¼, each of which had its own symbol. Some of the numeral symbols in Ahmes deviate somewhat from the forms given in the two preceding tables; other symbols are not given in those tables. For the reading of the example in question we give here the following symbols:

 Four (symbol characters) One-fourth (symbol characters) Five (symbol characters) Heap (symbol characters) See Fig. 7 Seven (symbol characters) The whole (symbol characters) See Fig. 7 One-half (symbol characters) It gives (symbol characters) See Fig. 7

Fig. 7.—An algebraic equation and its solution in the Ahmes papyrus, 1700 B.C., or, according to recent authorities, 1550 B.C. (Problem 34, Plate XIII in Eisenlohr; p. 70 in Peet; in chancellor Chace’s forthcoming edition, p. 76, as R. C. Archibald informs the writer.)
