Math problem in the second grade of primary school: a multiplication formula. Tintin regards one of the factors 2 as 5 and the product is 35. Think about the right product.
35/5=7
2*7= 14
Solution: Because Tintin regards 2 as 5 and gets 35, it can be deduced that the formula is 5*()=35, 35/5=7, where one factor is 2 and the other factor is 7, so the answer is 14.
