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=66=3 \cdot \ 2 \ \\ n=6 \ k ; k \in N \ \\ n=3 \cdot \ 2 \cdot \ k \ \\ \ \\ n=3 \ l; l \in N \ \\ \ \\ x=3 \cdot \ 2=6

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
