List method is to list possible situations and find the correct answer from them.

2. Solution 2: Leg lifting method

The leg lifting method is to lift one leg of the chicken and two front legs of the rabbit, so that the total number of legs is reduced by half. According to the number of rabbits = total number of legs /2- total number of rabbits.

3. Solution 3: Hypothesis Method

Suppose it's all chickens or rabbits. If they are all chickens, then the number of feet divided by 2 is the number of rabbits. If they are all rabbits, then the number of feet divided by 2 is the number of chickens.

Mathematics learning skills

Mathematical theorems, formulas, laws, etc. We should complement each other in recitation and understanding, and remember on the basis of understanding and comprehension. With these tools and our quick thinking, we can solve math problems with ease.

The stronger the self-study ability, the higher the understanding. With the growth of students, their dependence on teachers is gradually weakened, and their self-learning ability is constantly enhanced. Therefore, to form a good habit is to preview the new lesson before the teacher talks about it. See if we can deduce new formulas or theorems and understand new contents through the knowledge we have mastered.
