Theorem prove

We want to prove the sentence:

If the natural number n is divisible by six, then n is divisible by three.

From what assumption we started?

Correct result:

x =  6


6=3 2 n=6 k;kN n=3 2 k  n=3 l;lN  x=3 2=6

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
