Answer:
La historia de las matemáticas es el área de estudio de investigaciones sobre los orígenes de descubrimientos en matemáticas, de los métodos de la evolución de sus conceptos y también en cierto grado, de los matemáticos involucrados. El surgimiento de la matemática en la historia humana está estrechamente relacionado con el desarrollo del concepto del número, proceso que ocurrió de manera muy gradual en las comunidades humanas primitivas. Aunque disponían de una cierta capacidad de estimar tamaños y magnitudes, no poseían inicialmente una noción de número.

Broadly talking, there are main resources of economic growth: growth in the size of the workforce and increase in the productivity (output per hour worked) of that workforce. Either can increase the overall size of the economy however only a strong productivity increase can increase per capita GDP and earnings.
The economic increase is driven oftentimes by consumer spending and business investment. Tax cuts and rebates are used to return money to consumers and boost spending. Deregulation relaxes the rules imposed on businesses and has been credited with creating growth but can lead to excessive risk-taking.
