How to calculate the formula of the first volume of mathematics in the second grade of primary school
I don't know whether the parents or the children are asking questions. This teacher should have taught me, right?

There is no specific picture, I can only give you an example. The picture is as follows:

As can be seen from the figure, ① each bundle contains 4 balloons, one * * * 4 balloons and * * 16 balloons; ② If separated from the middle, there are 8 balloons on the left and 8 balloons on the right, *** 16 balloons.

So what is the multiplication formula? 4×4= 16 ? And then what? 8×2= 16;

What is the division formula? 16÷4=4 ? And then what? 16÷2=8。
