Is the smallest even number 0 or 2? What is the smallest even number

In the casual conversation, I found that everyone was confused about the question of "what is the smallest even number", and there have always been two opinions, one thinks it is 0 and the other thinks it is 2, and both of them are eloquent and impeccable. However, I have a different opinion: the emergence of new knowledge in textbooks always has certain limitations, which are restricted by many aspects such as students' knowledge level, cognitive stage, and knowledge system, so it must be studied within a certain range.

The wise old man clearly told us that for the convenience of research, multiples and factors should be studied within the range of non-zero natural numbers. The concepts of even and odd numbers are an extension of the concepts of multiples and factors, so they cannot be separated from the prompting of wise old men, and even numbers must be studied within the range of non-zero natural numbers.

In the textbook, the wise old man said: A number that is a multiple of 2 is an even number, and a number that is not a multiple of 2 is an odd number. Multiples are concepts that are put forward in the range of non-zero natural numbers, and it is obvious that 0 cannot be used as a multiple of 2, so 0 cannot be used as the so-called smallest even number in the knowledge system of the unit at the primary level.

From the point of view of the relationship between the knowledge and the back, when entering junior high school, the range of integers is further expanded, and negative numbers appear. Then the range of even numbers can be expanded, and the smallest even number is not 0, but there is neither the largest even number nor the smallest even number. In this sense, it seems not very relevant to study who is the smallest even number.

It is clearly stated in the teaching reference that "the smallest even number is 0", but it cannot be explicitly told to the students, and it does not need to be infiltrated to avoid confusion of concepts, indicating that the editors are aware of this. However, in the book "Goals and Exercises", which goes with the textbook, isn't it a contradiction to examine what is the smallest even number? Therefore, it is not the teachers and students who cause the conceptual confusion, but the metaphysical experts and scholars.

What is the smallest even number.

The smallest even number is 0.

An even number is a type of natural number, while 0 is a natural number, so the smallest even number is 0. As long as it contains a number of about 2, it is an even number; As long as it's a multiple of 2, it's even.

Natural numbers are orderly, infinite. Natural numbers are divided into even and odd numbers, composite numbers and prime numbers, etc.

Because: 0 is not included in the knowledge of multiples and factors.

The smallest even number, if it is in elementary school, should be zero, but after the introduction of negative numbers in junior high school, there is no smallest even number.

In the range of natural numbers, the smallest even number is 0. When studying odd and even numbers, 0 is excluded, so the minimum is 2, not 0. Within the range of natural numbers, the smallest even number of signage is 0.

When studying odd and even numbers, 0 should be excluded, so the smallest is 2, not 0.

This slide and merge question begins with clarifying the number in question. Range. In the textbook of the fifth grade of elementary school, it has been stated that it is in the range of non-zero natural numbers, so that the smallest even number is 2.

If in teaching and exams, it is first necessary to be clear in what range, if in the range of natural numbers, the smallest even number is 0.

What is the smallest even number.

The smallest even number is 0.

0 is a special even number. It is both the dividing line between positive and even numbers and the watershed between positive and negative odd numbers.

All integers are either odd (singular) or even (even). If a number is a multiple of 2, it is an even number (double) and can be expressed as 2n; If not, it is an odd number (singular), which can be expressed as 2n+1 (n is an integer), i.e. the remainder of the odd number (singular) divided by two is one.

No. There is no minimum even number.

No, even numbers are also negative.
