An influential proposal about aquiring mathematical knowledge is that it entails linking instruction-based concepts to intuitions derived from informal activities. In the case of non-positive numbers, informal knowledge is unlikely to emanate from observing physical objects, because non-positive objects or sets of objects do not exist. However, it…

The advance of science and technology, the rise of mass consumerism, the deterioration of families, and other factors have enormous implications for career counseling.
