Remember wat Ms Yeo taught non Math olympiad pupils abt the grid thing? Pic this question.
There are 10000000000000000000000000000000000000! to the power of 10000000000000000000000000000000000000000000000000000000000000000000!
squares on one side of a grid and another 10000000000000000000000000000000000000! to the power of 10000000000000000000000000000000000000000000000000000000000000000000!
squares on the other side of the grid. There are two towns: town a and town b. adjacent to each other. You can only move towards B which is the upper right - hand corner of the grid. (Right or up.) How many possible routes are there from town a to town b, when town a is at the bottom left - hand corner of the grid?
