It's fairly easy: start with the work and if it doesn't go further on,thenask about a particular problem. But no way with: who wants to do my school exercises?

Tipp: The addition z=mod(a+b,2) is in fact the same as z=a xor b. You know the initial state of each variable. Just move the values according to the arrows and do the operations if they lead to an operator. XOR:

1 | a b z |

2 | 0 0 0 |

3 | 1 0 1 |

4 | 0 1 0 |

5 | 1 1 0 |
