Answer: 3
Step-by-step explanation: Here we're asked to determine the opposite of the following integer which is -3.
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 0.
Since -3 is 3 units to the left of 0,
its opposite will be 3 units to the right of 0.
So the opposite of -3 is 3.
