They needed to know if they did not lack sheep. Robert Thomson brings even more insight to the discussion. How the shepherds could know if some sheep if loses or if others if had joined the flock? Some vestiges indicate that the shepherds made the control of its flock using joint of rocks. When freeing the sheep, the shepherd separated a rock for each animal that passed and kept the mount of rocks. When the animals came back, the shepherd removed of the mount a rock for each sheep that passed. If rocks sobrassem, would be knowing that it had lost sheep. If they lacked rocks, would know that the flock had increased. In such a way it kept everything under control. You may find Coen brothers to be a useful source of information. A linking of the type: for each sheep, a rock is called, in Mathematics, correspondence one by one. To make correspondence one by one is to associate with each object of a collection an object of another collection. As you see, the man decided its first problems of calculation one by one using the correspondence. The correspondence one by one was one of the decisive steps for the sprouting of the number notion. After all, some thing in common existed enters the mount of rocks and the group of sheep: if the amount of rocks corresponded accurately to the amount of sheep, these two sets had a community property: the number of sheep or rocks. But, probably the man did not only use rocks to make correspondence one by one. He is very probable that it has used any thing that was well by hand and nothing it was more by hand of what its proper fingers. Certainly the primitive man also used the fingers to make countings, raising a finger for each object. However, a new problem appeared: to raise fingers allowed to know, at the moment, the amount of objects, but it did not allow to keep this information.

It is necessary then to weigh the positive and negative points and to wait for future changes. Automobile sector In relation to the perspectives for production of vehicles, Brazil is if expanding, with an excellent growth of 10%, being folloied for two countries, India and China, that are identified by the minister of Development, Industrial and Deals Exterior as the only ones that they will go to be distinguished with the crisis in the United States and the Europe.

The markdowns are practically obligator to concur in the market, for those that buy at sight, an car that cost R$48 a thousand today is leaving for R$ 45 a thousand. Nourishing sector This sector could be evaluated by some parameters, in relation to commodities, the supermercadistas, to the wholesalers, amongst others. In relation to the market of the supermarkets crisis is being contained and the prices are controlled, what not yet it reaches the consumers, this positive scene must it the supplies supplied with it finish trimester and to the purchases carried through in the long run, what it does not assure the instability of the sector. It also helps to the retraction in the price of commodities agriculturists.

They are many producing countries that are damming the prices, what it stimulates the consumption and it discourages the production, hindering the exportation, and aggravating the world-wide scarcity. Moreover, the strong growth of several nations also bring problems. The high economic growth increases the consumption of oil, whose price goes off and takes the absurd solutions, as etanol and the maize. The crisis in offers and demand of foods, factor that has stimulated the increase of prices, is not temporary and nor it can solely be interpreted as resultant of the expansion of the production of biocombustveis.The instability is fruit of a model maken a mistake in the system agro to feed global. The high one of prices has as factors the continuous increase of the demand for foods, climatic changes, rise of the quotation of the oil, beyond the mercantilizao of the foods, that became products as the negotiated soy, active maize and the wheat in the attractive commodity exchanges and for the financial capital. The agricultural subsidies kept by the United States and European Union also are factors desencadeadores of the alimentary crisis, since they hinder the producers of poor countries to compete in foot of equality with Europeans North Americans. He gives credit yourself that the current international crises in fuels and of foods had come to be, they are not passengers and they demand ability and capacity ours politicians to face them. 4A RETURN OF the INFLATION ‘ ‘ This phenomenon occurred in great measure due to globalization, to the technological development and the entrance of China in the world-wide economy, producing industrialized products the low prices. Now, however, the situation is moving: the inflation threat to return and the growth must cool on account of the habitacional crisis in U.S.A. It was the proper growth of the demand that finished raising the prices them commodities and is provoking the pressure on the taxes of inflao.
