Question
The statement “When an integer is added to itself, the sum is greater than the integer” is ______.
Options
Always true
Never true
True only when the integer is positive
True for non-negative integers
Solution
The statement “When an integer is added to itself, the sum is greater than the integer” is true only when the integer is positive.
Explanation:
Suppose we take two integers one positive (+1) and other negative –1.
On adding 1 to itself, we get
1 + 1 = 2
Here, the sum is greater than the integer (+1).
Again, adding –1 to itself, we get
–1 + (–1) = –1 – 1 = – 2 Here, the sum is less than the integer –1.
