The positive numbers you gave are...
2, 3, 5, 7, 11, 17, 19
Their negative partners are...
-2, -3, -5, -7, -11, -17, -19
They are -19, -17, -13, -11, -7, -5, -3 and -2.
-2, -3, -5, -7, -11, -13, -17, -19
(-11) + (+19) = -11 + 19 = 8
19+(-11) is the same as 19-11. Therefore, the answer is 8.
19
actually, when adding a negative and positive it isn't always positive. for example: -19+8=-11. You should subtract the positive from negative like: 19-8=11.
-15 + 19 + (-26) + 11 = -41 + 30 = -11
