17. Module No#08
This chapter delves into the principles of discrete mathematics, specifically focusing on the application of the pigeonhole principle to prove the existence of certain properties among sets of integers or points in a plane. The fundamental aim is to showcase how pigeonhole logic can help derive relationships, affirm conditions, and establish the validity of mathematical statements across different scenarios.

What we have learnt
- The pigeonhole principle can be utilized to prove mathematical assertions involving distinct integers or points.
- Irrespective of the arbitrary selection of integers, certain pairs will always possess defined relationships, such as summing to a specific value.
- Mathematical proofs can demonstrate the availability of multiples of integers with specific digit representations.
Key Concepts
- -- Pigeonhole Principle
- A principle that states if n items are put into m containers with n > m, then at least one container must contain more than one item.
- -- Midpoint Formula
- The formula used to find the midpoint of a line segment defined by two endpoints (x1, y1) and (x2, y2) as ((x1 + x2)/2, (y1 + y2)/2).
- -- Decimal Expansion of Numbers
- A representation of numbers in the base-10 numeral system, consisting of digits 0 through 9 placed in specific positional values.
