Selam:)
Long long time ago my mother asked me to solve a puzzle she knew
as a child. I was in grade 8. I took the puzzle to the class and this
outstanding
Math teacher, Kifleyesu Adhanom ( killed in Massawa bombing) solved it
algebraically and mother was amazed at the so called algebra.
Here is the puzzle; enjoy.
There were three merchants with 9 camels carrying quintals of salt. They
made it to Kebesa to sell the salt; but they had to divide among
themselves equally.
The problem is camel number is carrying only one quintal, number 2 has
only 2
and the 3rd one only three and so on; that means number nine is
carrying nine quintals.
Could they possibly share the same number of camels and number of
quintals?
This puzzle is in honor of my deceased mom who taught me to be nothing
but
fair.
Thanks you all and good luck.

......It was during the end of the semester, our professor asked if we
knew
what the word "Alogorithm" stands for, a word which appredred so many
times
in our text books. (Big! class size 300+ students) .
None of us knew .... Later, the prof told us ....
Abu Abdullah Mohammad Ibn Musa al-Khawarizmi, 790-850 AD, Very little is
known about his early life.
Al-Khawarizmi ------> Algorizm ----->Algorithm
Al-Khawarizmi was a mathematician, astronomer and geographer. He was
perhaps one of the
greatest mathematicians who ever lived, as, in fact, he was the FOUNDER
of several
branches and basic concepts of mathematics. In the words of Phillip
Hitti, he
influenced mathematical thought to a greater extent than any other
mediaeval writer.
His work on algebra was outstanding, as he not only initiated the
subject in a systematic
form but he also developed it to the extent of giving analytical
solutions of linear and
quadratic equations, which established him as the founder of Algebra.
The very name Algebra
has been derived from his famous book Al-Jabr wa-al-Muqabilah. His
arithmetic synthesised
Greek and Hindu knowledge and also contained his own contribution of
fundamental
importance to mathematics and science. Thus, he explained the use of
zero, a numeral
of fundamental importance developed by the Arabs. Similarly, he
developed
the decimal system so that the overall system of numerals, 'algorithm'
or 'algorizm'
is named after him.
