Aunt Liu took a fruit from each of the two fruit bowls to Lily. There are several different methods.

Assuming that the first fruit bowl has m fruits and the second fruit bowl has n fruits, then there are m×n different ways to take a * * *.

Aunt Liu took a fruit from each of the two fruit bowls to Lily. It is necessary to analyze the number of fruits in each fruit bowl, and then use the principle of multiplication to find different methods. That is, if the first fruit bowl has m fruits and the second fruit bowl has n fruits, then a * * * has m×n different ways to take it.

Doing one thing can be divided into n steps. There are m 1 different methods in the first step, m2/different methods in the second step, and m×n/different methods in the n step, so there are M 1× M2×…× Mn.

Mathematical reasoning method:

1, inductive reasoning is from the local to the whole, from the individual to the general reasoning, in induction, we must first according to the individual known parts, appropriate deformation, find out the relationship between them, so as to summarize the general conclusion.

2. Analogical reasoning is the reasoning from special to special, and it is the reasoning between two similar objects. One object has certain properties, and another object has similar properties. In analogy, we should fully consider the reasoning process of known object properties, and then deduce the properties of analogy objects through analogy.

3. Deductive reasoning: Deductive reasoning is the reasoning from general to special, and the mathematical proof process is mainly carried out through deductive reasoning. As long as the major premise, minor premise and reasoning form of deductive reasoning are correct, then its conclusion must be correct, so we must pay attention to the correctness and integrity of the reasoning process.
