Strugging with truth tables? I made this app just for you - quickly generate truth tables from any boolean logic statement - it also includes an interactive tutor that teaches you how to solve truth tables step-by-step!

Truth Table Generator

This truth table generator can show you the results of boolean logic statements quickly.

Results

``````A  B  C  |  (  A  |  ~  B  |  ~  C  )  &  (  ~  A  |  ~  B  |  ~  C  )  &  (  A  |  B  |  ~  C  )  &  (  A  |  ~  B  |  C  )

Usage

Operators in order of evaluation. All identifiers must be uppercase.

Symbol Meaning
1 Always true.
0 Always false.
~ Takes one postfix argument. True if the arugment is false, and false if the argument is true.
+ Takes two arguments. True if exactly one of the arguments is true, false otherwise.
& Takes two arguments. True if both of the arguments are true, false otherwise.
| Takes two arguments. True if either of the are true, false otherwise.
-> Takes two arguments. False, if and only if the first term is true, and the second term is false.
<-> Takes two arguments. True if both arguments are the same, false otherwise.
/ Splits an expression, so that multiple expressions can be entered.

Implementation

This truth table generator is written in ruby by Samuel Williams. It uses a unique parsing algorithm which supports arbitrary complexity operators, precedence and runs in linear time.
