Rules

statement - statement - conclusion
All             +         All              =        All
All             +         No             =        No
All             +         Some      =        No Conclusion
Some    +        All                =        Some
Some    +         Some       =        No Conclusion
Some    +       No                =        Some Not
No            +       No               =        No Conclusion
No            +       All                =        Some not reversed
No            +      Some         =           Some not reversed
