The answer is 0.
Plus 2 plus minus 2 equals 0. The addition of a positive number (2) and a negative number (-2) cancels each other out.
2 + 2 - 4 = 0
4 - 7 + 14 + 2 - 19 + 6 = 0
1 + 1 - 2 = 0
Zero minus (or plus) any number is that number. To clarify: 0 - (-2) = 2 0 - (-36) = 36
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
