 For example:
 
-```
-123 -> x means that the signal 123 is provided to wire x.
-x AND y -> z means that the bitwise AND of wire x and wire y is provided to wire z.
-p LSHIFT 2 -> q means that the value from wire p is left-shifted by 2 and then provided to wire q.
-NOT e -> f means that the bitwise complement of the value from wire e is provided to wire f.

+- `123 -> x` means that the signal 123 is provided to wire x.
+- `x AND y -> z` means that the bitwise AND of wire x and wire y is provided to wire z.
+- `p LSHIFT 2 -> q` means that the value from wire p is left-shifted by 2 and then provided to wire q.
+- `NOT e -> f` means that the bitwise complement of the value from wire e is provided to wire f.
 
 Other possible gates include OR (bitwise OR) and RSHIFT (right-shift). If, for some reason, you'd like to __emulate__ the circuit instead, almost all programming languages (for example, C, JavaScript, or Python) provide operators for these gates.
