@OwenGregorian It's important to understand that the ABA membership has been dwindling over the past couple of decades, now down to about 1/3 of what it once was. It has become very left-leaning.
@z9czpm8jky@Math_files Take any four consecutive numbers, beginning with a number greater than 2. We looked at p-1, p, p+1,and p+2.
Divide each by 4. The remainders are all one of 0, 1, 2, 3. They must all be different. So one of them, p-1 or p+1, is divisible by four.
@adamcarolla I blame Hollywood. If it employed guys like Ruffalo and de Niro with regular work, they wouldn't have time to be stupid.

Learning math is like learning any sport. First, you learn some basics. Then it's practice, practice, practice. Then you learn more basic facts, followed by practice, practice, practice. And so on - and on. On the journey, you may need some coaching from the teacher. Just like sports.
