The role of mathematics in the real worldIn response to whether they think math is useful in the real world or not, I think many people would answer "yes". However, there would also be a few people who are hard-pressed to find an answer when asked to be specific in what ways they think math is useful. This is because they possibly haven't quite noticed that mathematics penetrates the so-called fields of social sciences, not to mention the natural sciences, and contributes to them.Mathematics will change society!Mathematics as a science to deepen cooperation between the scientific and industrial world supplies the mathematical concepts of matrices, differential calculus, integral calculus, and DeMoivre's Theorem. They are required for solving mathematical problems and their applications in Engineering.
