A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
symbol
An upside-down "V" symbol on a calculator typically represents the logical operation known as "AND" in Boolean algebra. It indicates that both conditions or inputs must be true for the overall expression to be true. In some contexts, it may also denote the logical conjunction in set theory or be used in other mathematical operations. Always check the specific calculator's manual for precise definitions, as symbols can vary by model.
variable
AND in Boolean algebra is represented by a dot, like multiplication. It can also be represented with parenthesis. "(A OR B) AND C" can be written as (A + B)C AND can also be represented with variables next to each other, just like in algebra: "A AND B" can be written as AB
The symbol in Boolean logic represents the operator "AND," which returns true only if both operands are true. It is often represented by an asterisk (*) or a dot (•).

The XOR symbol in Boolean logic represents the exclusive OR operation, which is true only when one of the inputs is true, but not both. This differs from other logical operators like AND and OR, which have different truth conditions.

A symbol that represents one or more numbers is typically referred to as a variable in mathematics. In algebra, these variables are often represented by letters such as x, y, or z. These letters are placeholders for unknown or varying values in equations or formulas.
