Fill in the blanks to make the following statements true:
(i) (-5) + (-8) = (-8) + (тАж)
(ii) -53 + тАж = -53
(iii) 17 + тАж = 0
(iv) [13 + (-12)] + (тАж) = 13 + [(-12) + (-7)]
(v) (-4) + [15 + (-3)] = [-4 + 15] + тАж



Answer -

(i) -5 + (-8) тАУ (-8) + (-5) [Commutative law of additions]
(ii) -53 + 0 = -53 [Additive Identity]
[Adding 0 to any integer, it gives the same value]
(iii) 17 + (-17) = 0 [Additive inverse]
(iv) [13 + (-12)] + (-7) тАУ 13 + [(-12) + (-7)] [Associative law of addition]
(v) (-4) + [15 + (-3)] тАУ [-4 + 15] + (-3) [Associative law of addition]
