What does justify mean in the context of proofs?

[Phymath]

when dealing with proofs, what does the word "Justify" mean? does it mean show an example or prove for all cases?

 

[mathwonk]

it means prove it. An example might "substantiate", or "confirm" a statement, or "lend credence" to it, but would not "justify" it.

 

[Phymath]

so showing an example would not be enough to "justify" a therom?

 

[mathwonk]

i only answer each question once.
