We have 2 + 2 = 5 which is false and 2 + 6 =7 which is also false
And we have the conditional that
F → F ...and this is ( believe it, or not ) ..... true !!!
The simplistic reasoning for this is that if we're willing to accept an original false statement in a one-way conditional, then we're willing to accept anything that follows..!!!
