Tamari lattice

Tamari lattice is a type of mathematical structure that can be used to help solve problems. A tamari lattice is made up of points connected together by lines. The points are like places on a map and the lines are like roads connecting those places. To use a tamari lattice to solve problems, you need to follow a specific set of steps. First, you look at the problem and draw a diagram of the points and lines that represent it. Then, you draw an arrow from each point to each other point it's connected to. Finally, you look at the arrangement of arrows, and use them to figure out the answer to the problem.
