Numbers are being represented in 2s Complement form Now A is given as 1 (0000 0001) 2’s complement of A (+1)= 0111 1111 Now what no will be added to make sum longest to stabilize (Carry at each stage) is 1111 1111 so Decimal value of B is -1 [...]

T -> Person speaking Truth H-> Head appears Given proposition , T H Case 1: Person is Type 1 , speaking Truth hence HEAD.

For example, the constraint that says “If A, then B, and if B, then A” should be transcribed in one of the following two ways, based on the configurations of the other variables in the diagram: You will run into reciprocal causation in the final constraint of this logic game. Here are the final diagrams that you should create: Notice how the reciprocal causation constraints are diagrammed. Be aware of the implications of these constraints. For instance, if $B$ is not sent (diagram B), then $A$ cannot… [...]
