For thousands of years, ethiopian merchants used a very sophisticated system of multiplication to calculate the price of goods on markets throughout the Horn of Africa and the Middle East.

In a reportage entitled "A Night Of Numbers - Go Forth And Multiply ", BBC 4 reveals how ethiopians used a similar mathematical approach to multiplications as modern computers do these days by using powers of two and additions, what is commonly known as the binary numeral system representing numeric values using 0 and 1.

World wide demonstrations were successfully organized on May 15 2009 by the committee of the International Network against Repression and Injustice in Ethiopia.

On this commemoration day of the 4th Year anniversary of the highly contested ethiopian election of 2005, Ethiopians in different parts of the world rallied at the United States Embassies in London, Berlin, Bern, Rome, at the White House in Washington DC, and at United Nation Office at Geneva. They appealed to the US administration for support in the struggle for freedom and justice in Ethiopia and the release of Birtukan Mideksa, Teddy Afro and all political prisoners.
