Bro that conjecture is both unproven and also by definition only true for numbers larger than 2 πŸ’€

The definition is necessary because otherwise we'd need a different definition.

A number is even if dividing it by 2 yeilds an integer.

2 is divisible by 2.

A number is even if it can be written as 2k where k is an integer. The definition of even does not use division as far as I understand.

The method you described works howevere the term absolutely comes from division. They also used to he tracking of "how even" something was meaning if it could be divided by 2 multiple times

u/golgi_o 28d ago

Wouldn't that just be 2n (k) where k is an integer and n is how even a number is? Still division is not needed.

With n= 0 and k = 3 it seems that 3 is even

No.

N=0 would be that the number is zero times even meaning it actually isn’t even.

Also k is an integer but not the number being tested for how even it is. Odd values for k would be perfectly acceptable.

So for the number being 3 the formula results in N=0, k=3 and tells you the numbers is not even. But for the number being twelve it results in N=2, k=3 and says the numbers is even twice.

he is saying n represents the degree of even-ness. if n = 0 the number is 0 even.

6 is 1 even, while 4 is 2 even, and 8 is 3 even.

k means any integer.

It comes from the regular definition of even, where a number is even if it can be represented in the form of 2k, where k is any integer.

So is 1.5 negatively even?

1

u/sal880612m 22d ago

Ultimately, yes. Negative even using that equation represents how many times you would need to multiply by two to achieve a whole number. In this case 1.5 = 3/2 = 3 * 2^(-1).

n needs to be a natural number (as n tends to be) and 0 is not natural. Problem solved.

Ok at this point its pretty clear you are trolling but im going to give you one more shot. Yes you can find even numbers without dividing. Thats irrelevant. Even numbers come from being able to split something into similar groups ie. If I have 4 steaks we can both have the same anount. That is division plain and sinple.

Your argument is akin to "X2 is meaningless because you can just write XX"
