Definition of Linear Programming:
a linear programming maybe defined as the problem of maximizing a linear function subject to system of linear constraints. The constraints maybe qualities. The linear function is called the objective function, of the form f (x, y) = ax + by + c

Steps:
0. Read the whole problem
1. Define the whole problem
2. Express the objective function and the constraints
3. Graph the constraints
4. Find the corner points to the region of feasible solution.
5. Evaluate the objective function at all the feasible corner points.

Post 6 - Permutation

Definition on Permutation:
One of many different ways that can be arranged. Another simple definition is schedule, order and arrangement.

Ways:
1! = 1 way
2! = 2 ways
3! = 6 ways
4! = 24 ways
5! = 120 ways
6! = 720 ways
7! = 5,040 ways

Explanation:
I am going to pick 7!, so why 7! = 5,040 ways? simple. you just have to expand it like this,
7 * 6 * 5 * 4 * 3 * 2 * 1, the answer will be 5,040.

Symbols:
N! = Permutation
! = Factorial
n = number selected

Permutation formula:

Post 5 - Geometric Progression

Introduction of Geometric Progression.
a Sequence of a number which is a quotient of any two successive members of a sequence that constant called Common Ratio of the sequence.

Explanation:
The formula and the calculation are the same as Arithmetic Progression, only the different is we have to find the common ration, not the common difference. for example:
