Options

• When two positive integers are added, we always get a positive integer.

• When two negative integers are added, we always get a negative integer.

• When a positive integer and a negative integer is added, we always get a negative integer.

• Additive inverse of an integer 2 is (–2) and additive inverse of (–2) is 2.

Answer 1

When a positive integer and a negative integer is added we always get a negative integer.

Explanation:

1. True, when two positive integers are added, the resultant number is also a positive integer.
2. True, while adding integers, if both the numbers have same sign, the resultant number also get that sign.
3. False, while adding the integers of different signs, the resultant number get the sign of greater number.
4. True, additive inverse of an integer is the same integer value, with opposite sign.
