Logical Operators Formula

The Formula

AND: TโˆงT=T; OR: FโˆจT=T; NOT: ยฌT=F

When to use: AND is strict (both must be true), OR is flexible (either works), NOT flips the result.

Quick Example

x > 0 AND x < 10 is True only when x is between 1 and 9 (e.g., x=5 is True, x=11 is False).

What This Formula Means

Operators that combine boolean expressions: AND (both true), OR (at least one true), NOT (opposite).

AND is strict (both must be true), OR is flexible (either works), NOT flips the result.

Why This Formula Matters

Used in every conditional statement, filter, and search in programming.
