In mathematics, imaginary numbers are numbers in the form of a+b*i, where a and b are real numbers, b≠0, i? =- 1, the quadratic equation of one variable is calculated in the formula "b? -4ac & lt； 0, the equation represents no solution in the real number range, but in the complex number range, the imaginary number in the complex number can be used to represent the solution of the equation.
Computational aspects of mathematics
Even occupies a dominant position in elementary mathematics. Its position in higher mathematics is also obvious. In addition to many theoretical subjects, advanced mathematics also has a large number of computational subjects, such as differential equations, computational mathematics, statistics and so on. With highly abstract theoretical equipment, it is possible for these disciplines to deal with complex computing problems in modern science and technology.
