Explanation:

The question is in French language. The translation to English is:

1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.

How many animals are going to the river?

Animal       amount

Rabbit            1

Elephants      6 (the rabbit saw 6 elephants)

Monkeys:       6 × 2 = 12 (2 monkeys per elephant)

Parrots:          12 × 1 = 12 (1 parrot per monkey)

Total:             1 + 6 + 12 + 12 = 31 animals ← answer
