Fundamental solution

Fundamental solution is a way to solve a problem. It is like a recipe that you can follow to find the best answer to a problem. To use a fundamental solution, you need to think carefully about the problem and then decide what steps you need to take to solve it. For example, if you wanted to find the area of a square, you could use a fundamental solution to help you figure it out. You would need to know the length of each side of the square, and then you could use a formula to calculate the area. The formula would be the fundamental solution to the problem.
