Q: How many people are there in total, 4 people in front and 6 people in the back? There are 11 prim

Elementary school students add themselves and substitute themselves into the question stem, before and after are not before and after, and the correct answer should be ten.

Because there is no mention of a person in the middle in the question, the elementary school student misunderstood, and the correct answer should be 4 6 = 10 people.

11 people, it should be that the teacher forgot to count elementary school students, and felt that the elementary school students were wrong.

4 students and 2 teachers play a table tennis singles match, and if every 2 people change their posture to play 1 game, a total of 15 games will be played.

If every 2 people play 1 game of sail defense, it does not mean that every 4 students and 2 teachers play 1 game, it means that every 2 people play 1 game.

4+2)x(4+2-1) 2=15

It turns out that there are 9 people, and 8 people go out is 9-8=1

6 more people came in, and on the original basis, it was 1+6=7 people.

So now there are 7 people in total.

There were 9 people, 8 people went out, 1 person left, 6 people came in, and now there are 7 people in the classroom. 9-8+6＝7。

There were originally 9 people in the classroom, 8 people went out, and 6 people came in. Now there are 7 people in total.

9-8+6=7, the original number of people minus the number of people out, plus the number of people who come in, is equal to the number of existing people.

There are also 9 people, because they are all people who go out and come in, but they are in different locations.

It should be 9-8+6=7 people, a total of 7 people.

Depending on the problem, the analysis can be calculated using an equation.

A: There are 7 people in total.

According to the title, the column formula can be: 9-8+6=7 (people).

There are seven people in total now.

9-8+6=7 (person).

There were originally 9 people in the classroom, 8 people went out, and 6 people came in. Now there are 7 people in total.

There are now a total of 7 teachers.

There were 9 people in the classroom, 8 people went out, and 6 people came in, so how many people are there now. This is a set of addition and subtraction mixed operations, that is, there are 9 people who remain unchanged, and 8 people go out, which is equivalent to subtracting 8 people, and 6 people coming in, which is equivalent to 6 more people, so it is 9-8+6=7, so now there are a total of 7 people.

The equation is: 45-10+6=35+6=41, so there were 41 people in the classroom.

The original question was Peppa Pig asking, I'm in line, there are 4 people in front and 6 people in the back, how many people are there in the team? It turned out to be 10 people and a pig, and it turned out that Peppa Pig was not human.

This actually depends on the situation to answer the question, if the first and second grade children are still learning addition and subtraction, the children do not have so much diffusion thinking, the teacher wants to test is 4 + 6 = 10, but we adults are more rich in thinking, resulting in the answer does not meet the teacher's requirements.

Because it is the child who does not see the question clearly, the question stems. Judging from the identity of Peppa Pig, there are 4 people in front and 6 people in the back. Piglets are not human.

1.It turned out to be 16 people.

2.There are 15 people who are closed = the original people - 8 people who go out + 7 people who go in.

3.The original person = 15 people who are in the bend + 8 people who go out - 7 people who go in = 16 people.
