Nwali, and Mr. Sam Zaslavsky read the manuscriptand offeredmanyexcellentsuggestions.
The readerwith an interestin the development of indigenousmathematicsin Africa
will find little informationin the mathematics history books except for a treatment of ancient Egypt.Of the few existing
accounts of other Africans' mathematical
development,one well-knownstoryis that
of the Damara people of SouthwestAfrica,
now called the country of Namibia; the
Damaras wandered in nomadic bands and
were among the least advanced, from the
point of view of technology,of all Africans. Their tale was firsttold by Sir Francis
Galton, the Britishscientist,explorer,and
of
in his book, Narrative
anthropometrist,
an Explorer in Tropical South Africa,
published in London in 1889. Here it is, as
retold in Howard Eves' In Mathematical
Circles:
. . . the primitive Damaras of Africa, in
barteringtwo sticks of tobacco for one
sheep as the rate of exchange, became
hopelessly confused when a white trader,
desiringtwo sheep, offeredfour sticks of
tobacco at once. Fraud was suspected by
the Damaras, and the transactionhad to be
revised and carried out more slowly. First
two sticks of tobacco were givenand one
sheep drivenaway, thentwo more sticksof
tobacco and the second sheep claimed.
When shown that the resultcame out the
same as the trader's originalproposal, the
tribesmenregardedthe trader as one possessed of magicpowers.
Eves concludes the narrativewith a telling
comment that is omitted frommost other
histories:
Yet, these Damaras were not unintelligent.
They knew preciselythe size of a flock of
sheep or a herd of oxen, and would missan
individual at once, because they knew the
faces of all of the animals.To us, thisform
of intelligence, which is true and keen
observation,would be infinitelymore difficult to cultivate than that involved in
counting.

by the Rev. SamuelJohnsonin theintroductionto his book, The Historyof the

rest are multiplesand compounds.Thus

less three, less two, less one, and then 20.
In the same way we continue 20 and
one, to 20 and four,and then 30 less five
(25), less four,and so on to 30, and so for
all figuresreckonedby tens.
There is no doubt that the digitsform
the basis of enumerationto a largeextent,
if not entirelyso. Five, ten, twenty,i.e.,
the digitsof one hand, of two, and the toes
included, and their multiples form the
different
stagesof enumeration.
Beginningfromthe firstmultipleof 20
we have Ogoji, a contractionof ogun meji,
i.e., two twenties(40), Ogota, three twenties (60), Ogorin,four twenties(80), Ogorun, five twenties (100), and so on to ten
twenties(200), when the new wordIgba is
used.
The intermediatenumbers(30 havinga
distinctterminology),50, 70, 90, 110, 130
to 190 are reckonedas: 60 less ten (50), 80
less ten (70), a hundredless ten (90), and
so on up to 200.
The figures from 200 to 2000 are
reckoned as multiples of 200 (400, however,whichis 20 X 20, the square of all the
digits,has a distinctterminology,
Irinwo or
Erinwo, i.e., the elephant of figuresmeaning the highest coined word in calculation,the restbeingmultiples)....
By a systemof contraction,elision,and
euphonic assimilation,for which the Yoruba language is characteristic,the long
termOrun-din-ni
(Egbeta or Egberinand so
on) is contracted to Ede or Ode, e.g.
Edegbeta (500) ...
and so on....
Summary. Thus we see that with
numbersthat go by tens fiveis used as the
intermediatefigure-fiveless than the next
higherstage. In those by 20, ten is used as
the intermediate.In those by 200, 100 is
used, and in those of 2000, 1000 is used.
The figure that is made use of for
calculating indefinite numbers is 20,000
(Egbawa), and in money calculation especially it is termedOke kan, i.e., one bag
(of cowries). Large numbers to an indefinite amount are so many "bags" or
rather"bags" in so manyplaces.
We have here an example of a vigesimal
system,one based on twenty,of whichwe
find numerousexamples in westernAfrica,
as well as in other parts of the world. In

A simpler system of divination, used
for minor decisions, calls upon Opele, a
lesser deity. For this purpose the oracle
casts a divining chain on which eight
half-pods or coins are strung at regular
intervals,with a greaterspace between the
fourthand fifthsymbol. The divinerpicks
up the chain in the middle and lets it fall
upon a flat surface in a two-column
arrangement.The appropriateodu is determined by the sequence of convex and
concave surfacesof the half-pods,or heads
and tails on the coins, and the interpretationis exactly as with the palm nuts.
Some authors, including Ojo, claim
that there are 163, or 4096 odus (roads of
Ifa), while others state that there are as
many as 164, or 65,536. Bascom maintains
thatthe numberis precisely256.

brutalityof racism. Every time I came in
touch with white people, I was abused and
spat on because of my so-called "Niggerhood"....
When I was enrolled in Soldan High
School in February 1957 (at the age of
fourteen),I had a personal interviewwith
one of the assistantprincipalsby the name
of De Shields. He told me that while in
Booneville [State ReformSchool], I made
an excellent academic record for myself
and that I could possiblywin a scholarship
if I applied.
For the firstcouple of weeks,I enjoyed
school work,and I was becomingabsorbed
in science, history, and literature stud-
ies....
Then one night around 1:30 police
banged on our door and threwtheirflashlights in my face demanding "Are you
Frank Chapman?" I was taken to the Page
and Union police station and chargedwith
car theft. The police knew that I didn't
steal the car but they wanted to clean up
the books, and I was a likely suspect
because I had just gottenout of Booneville
for car stealing....
1957 was a decisive
year in my life because this was the year I
gave up all hope of ever livinga so-called
normal life. I rationalized that with my
past record,the police would neverlet me
alone anyway,so I mightas well make the
most of it.
Chapman proceeded to "make it" in the
only way he knew. Between crimes were
several sojourns in the juvenile home and
the state hospital for the mentallyill. At
last he made his way to Chicago early in
1960, wherehe obtained a job in a hospital
and was marriedat the age of seventeen.
AfterI got marriedI wantedto make it
work. I got a job in Evanston, Illinois
workingas an assistantprinter.I averaged
about eighty-seven dollars every two
weeks. This was just not enoughmoney to
support my family.... We separated. Our
separationhad nothingto do withthe way
we felt toward each other; it was simplya
matterof survival.On the nightwe separated, I felt total despair,because this was
one thing in life I wanted....
I returnedto St. Louis penniless and
desperatein February1961. My plans were
to organize a stick-upringand rob until I
accumulated enough money to supportmy
familycomfortably.
I forget on just what day in March
1961 it was, but I rememberit was dreary
and raining.I was at a fellow'shouse I had
just recentlymet, drinkingwine, when he
suddenly suggestedto me, "Let's stick up
that shoe shop and get some money." I
replied "Okay." I walked into the shoe
shop with a loaded twenty-twopistol. An
old white man about seventyyearsold was
sittingon a bench. When I said, "This is a
stick-up," he leaped from the bench and
grabbed me by the arm and the hand the
pistol was in. In the process of wrestling,
the gun went off and a bullet enteredthe
head of the old man. To this day, I can't
rememberall the thingsI did rightafterI
killed this man. I know I ran for blocks
before I regained control of myself.The
man I committedthis crime with,I hardly
knew, for we had only met two days
beforethisincident....
On April 6, 1961, I was apprehended
by the police in Evanston, Illinois for
suspicion of drug addiction. Two weeks
later I was in St. Louis facinga charge of
first-degree
murder.
Presently,I am in prison,confinedin a
box-like cell, which is about six feet in
width,seven and a half feet in length,and
ten feet high....
Prison is a place where a
few men acquire new dreams and new
hopes, and where most men lose even the
ability to hope for anything except a
successful crime career....
But I left the
courtroom with this conviction; I must
know the truth about myself, I must
become conscious of whateverforceshave
shaped my lifeand made me what I am. On
that day life forme took a new and sudden
turn. I wanted to live only to know myself
better,and the world. I wanted to discover
formyselfmy own humanity.
In many respects prison is almost an
ideal place for study, for one has a great
deal of leisure time....
First I enrolled in
school, in the eighth grade. In a few
months I graduated. This was the second
time I had graduatedfromgradeschool. As

Reflectionsof this nature have led me
to the conclusion that the most pressing

political leaders is the layingof ideological

thereby arrivingat some concrete conception of her historical mission.
