A even number is 2 and all of it's multiples.An odd number is any number between 2 even numbers.Any digit that ends with the fallowing digits that is over one(additional the digit 1 is odd and 0 is even)is an even number:02468.Any other number is odd.
An even number plus an even number is always an even number.An odd number plus an odd number is always an even number.An odd number plus an even number is always odd.
Lets apply:
k+h=?
We don't know what numbers the letters k and h replace.What we do know is k replaces an even number and h replaces an odd number.Therefore,we should conclude that "?" is an odd number.
If you can't make sense of this you either don't know any numbers or you you don't actualy belive that you can which results in you not trying.ANABODY AND I MEAN ANYBODY OVER AGE 2 THAT KNOWS THERE NUMBERS AND HAS AWARENESS OF THEMSELVES EXISTANCE AND HAS NO MAJOR MENTAL ILLNESSESS THAT DISABLE REASON AND CAN COMMUNICATE CAN MAKE SENSE OF THIS!!!SERIOSLY!!!
also a number times nine equals that number times 8 plus ten subtracted one.
Got that?
