TITLE: "false implies true" is a true statement
QUESTION [15 upvotes]: In algebra, one lesson we took was about logic.
We learned that it is a true statement or logical expression to say that if a Beijing was the capital of the US then the moon existed last night, as this is convenient with a false statement implying a true one being a true statement.
Agree?

REPLY [6 votes]: You want "real life", eh?  
Let (P) be the statement

If the policeman sees you speeding, then you will have to pay a fine.  

This is true.  But it could happen you have to pay a fine because you failed to shovel the snow from your sidewalk.  So you have to pay a fine even though you did not speed.  But this does not mean that (P) is false.
