Key Features

• Field: Mathematics
• Applications: Calculus, algebra, computer science
• Example: “The function f(x) = 2x + 3 is a linear function.”

7. False (F)

In computing and logic, F stands for False, a Boolean value used to denote that a statement or condition is not true. Boolean logic operates on true/false conditions and is essential for computer programming and digital circuit design.

Key Features

• Field: Computing, logic
• Applications: Software development, logic gates, algorithms
• Example: “The condition returned F, meaning it did not meet the criteria.”

8. Fraction (F)

In mathematics, F represents a Fraction, a numerical quantity that is not a whole number, expressed as one number divided by another (e.g., ½ or ¾). Fractions are used in a variety of mathematical applications to represent parts of a whole.

Key Features

• Field: Mathematics
• Applications: Arithmetic, algebra, geometry
• Example: “A fraction like ¾ represents three parts of four.”

F in Social Media and Technology

9. Facebook (F)
