I ended up with some pretty basic questions during my prep for GMAT and was hoping to find some help.
1) Is 0 considered even? (I was wrong on occasions when I assumed it was) YES. 0 is even
2) Are -2,-7,-11 etc.., considered primes also? Negative primes dont exist. Primes are positive integers
3) If an equation has a -/+ sign to it, can it be 0? For instance, for the examples, -n=m+1 or (-2)^(-n), can n still be 0? (-2)^(-n) -----> n = power could be zero. Anything raised to zero is 1.
4) Are -2,-4, -6 etc.., considered even integers ? Right on ! YES
5) Is 0 a multiple of every number when solving "multiple" problems. YES. 0 is a multiple of every integer CAUTION : 0 is never a factor. Divide by zero leads to undefined values. Any statement alluding to divide by zero on GMAT can be "eliminated"
6) is (-2)^0 = +1? (Since any number ^0=1) Right on ! YES
In regards to (2), keep in mind that for any negative integer -X, without knowing anything else about X, we know that it has at least four factors: X, -1, -X, 1
RE: (3), any time you see "-n" in an equation, it is equivalent to (-1)n. Therefore, n could be zero. "-n" is just a confusing notation; it does not indicate that n is a negative number.
