# What is numerical analysis in mathematics?

Numerical analysis, area of mathematics and computer science that creates, analyzes, and implements algorithms for obtaining numerical solutions to problems involving continuous variables. Such problems arise throughout the natural sciences, social sciences, engineering, medicine, and business.

Accordingly, why do we use numerical methods?

Most mathematical models used in the natural sciences and engineering are based on ordinary differential equations, partial differential equations, and integral equations. Numerical methods for solving these equations are primarily of two types. Such numerical procedures are often called finite difference methods.

What is numerical and analytical solution?

In contrast to this, some problems are solved via other means. If, instead of using the quadratic formula, you try a lot of values for x and y, this is a numerical solution. Some problems simply do not have analytical solutions and must be approximated using numerical methods -- for example, many complicated integrals.
