Answer: 11
Step-by-step explanation: Think of the opposite of an integer in terms of a number line. The opposite of an integer is the same distance from zero as the original integer but on the opposite side of zero.
On the number line, we can see that -11 is 11 units to the left of zero, so its opposite will be 11 units to the right of zero.
So the opposite of -11 is +11.
