(I believe you meant "two" so we'll go by that)
Claudio has 34 and loses 2, he has 32. Simple subtraction. Next, Claudio divides the toy cars up between four people (and that's including himself). So, you'll take 32 and divide it by 4 which should give you your answer.
34-2 = 32
32/4 = 8
Each child will receive 8 toy cars.
