Answer 2

Answer:

i. False

ii. True

iii. True

iv. False

v. False

Step-by-step explanation:

i. When you add you negative Integers, the result is also negative.

$( - 4) + ( - 3) = - 4 - 3 = - 7$

ii. Two negatives, when multiplied result in a positive number.

$( - ( - 4)) = ( - 1) \times ( - 4) = 4$

iii. The difference of two Integers is always an Integer.

$3 + ( - 4) = 3 - 4 = - 1 \: belongs \: to \: i$

iv. 0 is an identity of addition.

$3 + ( - 3) = 3 - 3 = 0$

v. Sum of a positive and a negative Integers may be negative, positive or 0.

$3 + ( - 1) = 3 - 1 = 2$

$also \: 3 + ( - 4) = 3 - 4 = - 1$

Hope this helps
