+
+## How we usually find solutions and why this is problematic?
+
+- We search for code example instead of algorithms.
+- We copy and paste and do testing on trial&error principle.
+- We don't take enough time to properly understand problem we a re trying to solve.
+- Brute force solutions we make are usually not optimized
+
+---
+
+## Math is horrible and I don't need it!
+
+- Well, YES :) Math can be horrible but also beautiful to implement.
+- Disregarding math is disregarding thousands of years of knowledge.
+- Math is not only for scientists.
+- Good algorithm is as optimized as your code is when you are done with it.
+- Math is the search for patterns and anti-patterns in natural universe and making these findings into tools accessible to ordinary people.

+## Coordinate Geometry
+
+A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

+## Linear Algebra
+
+Linear algebra is the branch of mathematics concerning linear equations such as. linear functions such as. and their representations through matrices and vector spaces.

+## Vectors and spaces
+
+- Space vector also called linear vector
+- Vector = magnitude + direction
+- Example: velocity vector (5kmh/west)

+## Shortest path problem
+
+In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.
+
+Shortest path (A, C, E, D, F) between vertices A and F in the weighted directed graph
