Question

l→ m
can someone help me with this

Answer 1

This means if l is true then m is true in an abstract kind of a way. For example, l could be "eating a good meal" and m could be "I'm satisfied right now"

So if l is true, then m is true would mean eating a good meal makes you satisfied right now. But just because m is true, doesn't mean l is true. You could be happy because you won the lottery for example. But you can't ever have a situation where l is true and m is false because you ate a good meal and eating good meals always makes you satisfied!
