Question

anonymous · Answer

well this question is horrible. Technically if a number is divisible by any real number

anonymous · Answer

but i think it is valid for what your teacher is trying to say

shane_b · Answer

It's a valid definition because both 2 and 3 are prime numbers.

anonymous · Answer

even though technically any number is divisible by and non zero number -.-

anonymous · Answer

I haven't encountered a problem with that definition when I tried out numbers up till 60. so i guess it is good.

shane_b · Answer

A better definition would have been: ""if a number is evenly divisible by 2 and evenly divisible by 3 then it is evenly divisible by 6""

If a number k is divisible by 2 and 3, then 2*3*n=k.
=> 6*n=k
=> k is divisible by 6.
maybe something like that helps D: i dunno..
