Question

Which of the following statements is not true?

• A. The sum of two integers is always an integer.
• B. The difference of two integers is always an integer.
• C. Sum of four integers can never be zero.
• D. -14 > - 8 - (-7)

Answer 1

Answer: (C), (D)

The correct options are
C

Sum of four integers can never be zero.

D

-14 > - 8 - (-7)

We know that addition and subtraction of integers follow closure property. So, the first two statements are correct.

Consider four integers 3, 5, -6, -2.
The sum of these integers
= 3 + 5 + (-6) + (-2) = 0

Here,
-8 - (-7) = -1 then,
-1 > -14

Therefore, statement iii and iv are not true.
