I cannot say that I was born to be a mathematician. I followed a path that led me to mathematics. As I went through the steps, I thought why not continue. Also, I must admit that my father was very demanding and followed me closely. I had faith in what I was doing. But there is no talent without work. Until the end, I did not know what I wanted to be. My parents wanted me to opt for medicine. That subject is above my human capacity. I am very emotional. I worked as a team with my girl friends and we said to ourselves: "why not do the maths" and we registered in the preparatory class for "Fontenay-aux-Roses".

Thanks to his encouragement, three years after meeting him, I obtained my doctoral degree and we got married.

With respect for commitments, organization, and love, the big African family can make you lift mountains and allow you to live your life as a wife and mother. Because on this side, since mathematics is brain-based - if the brain has problems, mathematically, it cannot go far - a mother's attention and brain are occupied by her child during at least nine months of pregnancy, and nine months of breastfeeding, i.e. eighteen months per child, so for five children that is about eight years. Eight years when the laboratory of the mind is idling. If this laboratory is slowed for eight years, when it reopens, is it at the same level as one that worked full time, that of the man? Then draw your own conclusions.

"Yao crack" is a comic strip made up of about twenty titled sketches, such as "Yao and Thales", "mathematical speaking" etc. Thanks to the drawings of our talented cartoonist Jess Sah Bi the scenes are full of humour and portray some of the difficulties that the African child faces in mathematics. As soon as a mathematics teacher says to a child (pupil or student) "go to the board", he sweats like Yao on the cover. We want to demystify mathematics to make it accessible to as many children as possible. ... Mathematics is at the base of all science and technology, both as a way of thinking and as an instrument of inquiry.

After recalling the history of the CFA franc, which exists only in relation to the French franc to which it has been tied by a fixed parity since 1948, the author discusses the possibility and the consequences of a devaluation of the CFA. The fixing of parity is one of the principles underlying the strength and credibility of the CFA franc. According to the monetary agreements, the parity of the CFA can only be modified if all the Member States agree. Unanimity never seems to have existed before for a change of parity. Assuming it is done tomorrow, the effects on African economies are likely to be catastrophic. Moreover, it is not certain that this devaluation resolves the fundamental problem which remains that of the relationship between the prices of exported products and import prices, that is to say the terms of trade whose variations reflect the enrichment or impoverishment of a country according to the evolution of world prices. Since 1970, most of the thirteen countries in the CFA zone have seen their terms of trade deteriorate from year to year.

The woman has always brought a lot of tradition and maternity. She is a wife, mother, educator, economic and social development officer. She has a very important part to play in development. As for her emancipation and evolution, she can only follow the emancipation and evolution of our states.

I hope that in Africa many women are devoted to science (law, physics, chemistry, etc.). If a woman wants, she can do more. I especially congratulate "Amina" for the progress made since its creation. It is a privileged instrument for the emancipation of the black woman. Continue to allow women from all walks of life to express themselves. Congratulations and thank you to Amina! All women must support you!
