माना कि
a = 1
b = 2
c = 3
विकल्प 1:
a + b = b + a
⇒ 1 + 2 = 3
⇒ 2 + 1 = 3
⇒ 3 = 3
विकल्प 2:
a – b = b – a
⇒ 1 - 2 = -1
⇒ 2 - 1 = 1
⇒ -1 ≠ 1
विकल्प 3:
a × b = b × a
⇒ 1 × 2 = 2
⇒ 2 × 1 = 2
⇒ 2 = 2
विकल्प 4:
(a + b ) + c = a + (b + c)
⇒ (1 + 2) + 3 = 6
⇒ 1 + (2 + 3) = 6
⇒ 6 = 6
सही उत्तर विकल्प 2 अर्थात a – b = b – a है।
