zero?
It is 2.
3 + 0 = 3
Because adding a negative is the same as subtracting a positive. In other words, minus a plus is he same as plus a minus. For example 5+ (-3) = 5-3 = +2 5 -(+3) = 5-3 = +2 Remember minus a plus = = minus plus a minus = minus plus a plus = plus minus a minus = plus
-2 -1 0 1 2
This is (3x +2)2 so if x is an integer/3, this expression is the square of an integer so cannot be prime. Anything else, and it's not even an integer.

an integer plus and integer will always be an integer. We say integers are closed under addition.
It cannot be done. The basic rules of math. odd integer plus odd integer = even integer. odd integer plus even integer = odd integer. Always. odd integer plus odd integer plus odd integer = odd integer. Always.
This is (3x +2)2 so if x is an integer/3, this expression is the square of an integer so cannot be prime. Anything else, and it's not even an integer.
Any positive odd integer can be expressed in the form of ( 2k + 1 ), where ( k ) is a non-negative integer. When dividing this expression by 6, the possible remainders are 1, 3, and 5, corresponding to the cases where ( k ) is congruent to 0, 1, or 2 modulo 3, respectively. Thus, an odd integer can be represented as ( 6q + 1 ), ( 6q + 3 ), or ( 6q + 5 ) for some integer ( q ). This shows that every positive odd integer fits one of these forms.

1/x + 1/2x + 2 = 2/3; 3/2x = -4/3; -8x = 9 (2 + 1)/2x + 2 = 2/3 3 + 4x = 4x/3 9 + 12x = 4x 8x = -9 x = -1 1/8 which isn't an integer but fits the stated conditions If you're doing A+ the answer is 2.
Yes. ie) -8-3=x The problem would change to: -8+(-3)=x x=-11 So just make it a negative plus a negative.
sqrt 9 = +3 or 3 3 - 7 = -4 -3-7 = -10 the sum is an integer
