Romberg's method

Romberg's method is a way of finding the exact answer to a math problem. It's like a special calculator that can be used when regular calculators can't give you the answer. Here's how it works:
First, you start with a problem that you want to solve. Then, you break it into small pieces and figure out the answer to each piece. Once you have all the pieces, you add them all up together to get the exact answer to your problem. The method uses a 'table' to help you keep track of the pieces by writing them down in order so they can be added together.
