HighernumeralsSenaand heh existed, but were hardlyusedin
arithmetic: e.g., 10,000,000 is usually written'v^.
Eachmultipleof unity from 1 to 9 had a separate name,and
in hieratic each of the corresponding groups was formed into a
distinctsymbol. Thesamewas the case withthe tens from 1 to 90,
but the hundreds, etc., wereexpressedin Coptic as multiples of
100, etc. — "three hundred," "three thousand," "three ten-thou
sands," etc. and the Egyptian nomenclature was probably
much the same as the Coptic : for these againthe hieratic forms
ligatures,but they are less specialised thanthosefor the units and
tens. I will not now attempt to explain the forms and names of the
Egyptianintegralnumerals.
No mathematical expressionfor infinity has been found: for zero
•^^ auti (?) occurs in Ptolemaic texts. At an early periodt T

neferseems to stand for o in subtraction, etc., properlymeaning
"good,""level."



  1. Fractions. The only fractions that the Egyptians could
    expresswerethe divisions of unity y4, \, \, \, \, etc., but there was
    no limit to the divisor, e.g., -yJ^ occursin PI. XIII, No 33. For i
    theypossesseda special sign / and a special name£s, in Coptic
    <ToC,XOC. The sign in its early forme=£- is believed to repre
    sentthe outline of one side of the human bodyup to the arm-pit,
    and thence downthe inner sideof the arm. J The literal meaning
    of ks is " side," thence" one side," " one half."
    All the other fractionsare expressed in hieroglyphicsby meansof
    a compound with<=>. Thus 1 1 1 is 3, but p=j^ ^, |=> ^
