For a number to be 6, it is necessary that this number must be more than 2.
But for a number to be more than 2, it is sufficient for it to be 6.
hihi, is this correct? have i grasped the necessary and sufficient conditions concept?

Being at least 35 years old is a necessary condition for becoming President of the United States, but it is not a sufficient condition. That is, nobody can be President who is less than 35, but many people are 35 or older without being President
Being a number greater than 2 is a necessary condition for being the number 6, but it is not a sufficient condition. No number that is not greater than 2 can be 6, but many numbers are greater than 2 without being 6.
Being the number 6 is a sufficient condition for being greater than 2, but not a necessary condition. The numbers 5 and seven, for example, are both greater than 2, but neither of them is 6.

If reminiscence serves continuity over the area in question is the two a sufficient and necessary circumstance. i think of the fact of equality is an 'if and provided that'. remember that the by-product can basically exist at factors in an era if the function is non-supply up therein.
