1. Root Finding Methods: These techniques aim to determine the solutions or "roots" of equations by providing approximate values for unknowns. Examples include the bisection method, Newton-Raphson method, and secant method.

2. Interpolation and Extrapolation: Interpolation methods estimate values between known data points, while extrapolation methods extend predictions beyond given data. They are valuable for filling in missing information.

3. Numerical Integration: Numerical integration methods approximate the area under a curve or the integral of a function when exact solutions are challenging. Techniques like the trapezoidal rule and Simpson's rule are commonly used.

4. Differential Equation Solving: Numerical methods solve differential equations that describe relationships involving rates of change. Techniques like Euler's method and Runge-Kutta's methods provide numerical solutions.

5. Optimization Methods: Optimization methods determine optimal values for variables to maximize profits, minimize costs, or optimize performance in specific objective functions.

6. Linear Algebra Operations: Numerical methods assist in solving systems of linear equations and performing matrix operations, which are crucial for problems involving multiple variables.

7. Error Analysis: Error analysis is important for understanding and managing errors that arise during numerical calculations. It helps assess the accuracy and reliability of obtained results.
