# Mathematical equations related to the topic of programmability:

Programmability refers to the ability of a system, device, or software to be configured, controlled, and customized through the use of programming languages, scripts, or codes. This characteristic allows users to create, modify, and implement specific behaviors, functions, or features tailored to their requirements. Programmability is essential in various fields, including computer science, engineering, and electronics, as it enables the development of versatile and adaptable systems that can cater to a wide range of applications and user needs.

Here are a few key equations and concepts:

1. **Time Complexity - Big O Notation**

Time complexity is a measure of the amount of time an algorithm takes to run as a function of the size of the input. It is often expressed using big O notation, which describes the upper bound of an algorithm's growth rate.

   O(f(n))

Here, `n` represents the size of the input, and `f(n)` is a function that describes the growth rate of the algorithm.

2. **Space Complexity - Big O Notation**

Space complexity is a measure of the amount of memory an algorithm uses as a function of the size of the input. It is also expressed using big O notation.

   O(g(n))

Here, `n` represents the size of the input, and `g(n)` is a function that describes the growth rate of the algorithm's memory usage.

3. **Recursion**

Recursion is a programming technique where a function calls itself as a subroutine. A common example of this is the Fibonacci sequence, which can be defined using the following recursive formula:

   F(n) = F(n-1) + F(n-2), for n > 1
   F(0) = 0
   F(1) = 1

4. **Boolean Logic**

Boolean logic is a subarea of algebra used in computer science and digital electronics. It deals with true and false values represented by 1 and 0, respectively. The key operations in Boolean logic are AND, OR, and NOT, which can be represented by the following truth tables:

**AND**

   A | B | A AND B
   0 | 0 |    0
   0 | 1 |    0
   1 | 0 |    0
   1 | 1 |    1

**OR**

   A | B | A OR B
   0 | 0 |   0
   0 | 1 |   1
   1 | 0 |   1
   1 | 1 |   1

**NOT**

   A | NOT A
   0 |   1
   1 |   0

These are just a few fundamental concepts and equations related to programmability and computer science.
