| (i) The addition and subtraction of integer cannot be represented on the number line. |
| (ii) For any three integers a, b and c, \[(a+b)+c=(a+c)\,(b+c)\]. |
| (iii) Under addition, the integer 1 is its identity. |
| (iv) The product of even number of negative integers is negative. |
A)
(i) (ii) (iii) (iv) T T F T
B)
(i) (ii) (iii) (iv) F T F T
C)
(i) (ii) (iii) (iv) F T T F
D)
(i) (ii) (iii) (iv) F F F F
Correct Answer: D
Solution :
(i) False on number line, addition and subtraction of integers can be represented. (ii) False, \[(a+b)+c=a+(b+c)\] hence, the addition of integers is associative (iii) False, The identity of integers under addition is zero. (iv) False, The product of even number of negative integer is positive.
