According to the problem description, the female squirrel picked up 32 pinecones, and the little squirrel picked up 17 pinecones. After the squirrel gave her some pinecones, she needed to find out how many pinecones her mother finally had.
Because the little squirrel gave his mother some pinecones, it can be expressed as subtraction. The final result is 32+( 17-x), where x is the number of pinecones the squirrel gave to his mother.
Simplify it and get 32+17-x = 49-x. Therefore, the number of pinecones that my mother finally owns is 49-x.
It should be noted that the squirrel mother needs to store the pine cones well to prevent them from being too moldy or stolen by other animals. It is suggested that the extra pinecones should be placed in a dry, ventilated and cool place to ensure the quality and freshness of pinecones. In addition, the squirrel mother also needs to pay attention to the nutritional needs of the little squirrel and feed the little squirrel in time to ensure its healthy growth.
