An integer N is less than its opposite. Which of the
following must be true of the integer?

The integer must be negative (less than 0)

Step-by-step explanation:

The opposite of a number is the same number but but with the opposite sign (+/-). E. G. The opposite of (+)2 is -2.

If N is less than its opposite, than it means that it is negative as its opposite will be positive (greater than 0). E.g. If N=-2, its opposite would be 2.

2>-2
