In a small town lived a close-knit family where every relation could be expressed through simple symbols. For instance, when they said A × B, it meant A is the father of B, while A ÷ B meant A is the mother of B. The younger ones were often introduced with A + B, meaning A was the daughter of B, and the bond of brotherhood was shown by A – B (A is brother of B). One day, the children in the family turned these symbols into a playful code. Instead of introducing their parents and siblings in words, they spoke only in symbols. "Look," giggled little Meena, "M + N ÷ O!" Everyone laughed, because they knew it meant Meena was the daughter of N, and N was the mother of O, making her O's sister. What started as a code soon became a family game, making the bonds of father, mother, daughter, and brother not just relations, but symbols of love and togetherness.
