"If the cistern has an inlet pipe and an outlet pipe, it takes five hours for the inlet pipe to fill up with water, and three hours for the outlet pipe to drain the water, and if the inlet pipe and the outlet pipe are turned on at the same time, how long does it take to fill the entire pool?"

"Which ghost came up with this topic, is it so 'maverick'?"

Looking at Mu Bai's topic, Jiang Chen was speechless.

Isn't it pure and wise to put water into the water while releasing it, and this is what elementary school students receive today?

On this topic, it is better to adapt the chicken and rabbit in the same cage.

Mu Bai agreed with a look of agreement, and the chicken nodded like a rice peck, and echoed: "I also think that there is a problem with the person who compiles the teaching materials, why do you drain water while draining, doesn't this teach children to waste water resources!" Obviously, you can make up the same topic in another way.

Jiang Chen nodded: "That's it, don't do this question!" Garbage topic, let's look at the next one.

"The combined ages of Xiao Ming and his mother are a total of forty years old, and it is known that Xiao Ming was ten years old two years ago, and asked how old his mother will be in five years."

After reading the topic, Jiang Chen looked pained.

Is this a question that people can come up with?

Can this kind of thing really be shown to children?

"I didn't do this either." Jiang Chen went straight.

Mu Bai looked strange: "Why?" This question is not very good! I want to do it, I can't encounter a problem and don't do it, I have to practice more!

Jiang Chen looked helpless.

"Then you do it."

After carefully studying for half a day, Mu Bai listed the equations according to the method in the textbook, and gave Jiang Chen the answer after the calculation was completed.

"Five years later, Mom is thirty-three! Jiang Chen, I figured it out! Mu Bai said happily.

"Jiang Chen, is my answer correct?"

Jiang Chen smiled bitterly: "The answer is correct, but didn't you find that there was anything wrong with this question?"

Mu Bai looked strange: "What's wrong?"

Jiang Chen sighed and said, "When my mother is thirty-three years old, how old is Xiaoming?" Hearing

this, Mu Bai seriously calculated again.

"Seventeen! Is something wrong? Mu Bai looked puzzled.

Jiang Chen looked strange: "Then when Xiaoming was born, how old was his mother?"

Mu Bai simply calculated, saw the answer, and was stunned.

"Sixteen, this age, isn't something wrong? Can't you have a baby at 16? "

Isn't it just sixteen to give birth, what's so strange, how young this mother is."

Jiang Chen smiled bitterly and said, "Physiologically it is possible, but humanitarianly, it is not."

"Why?" Mu Bai looked strange.

"Because human beings are only in high school at the age of sixteen, their minds are not sound, and even part-time work is considered child labor, and getting married and having children under such immature conditions is an irresponsible behavior for the family, for the children, and for themselves, both men and women." Jiang Chen explained.

Sixteen years old, in the Dragon Kingdom is still an early love!

Although with the passage of time, the situation of early adolescent love is more and more common, the age of sixteen is the age when the spring heart is budding and the yearning for love.

But if such a thing as having a child at the age of sixteen appears in primary school textbooks, will it really not have a bad impact?

Except for the October pregnancy, that is to say, Xiaoming's mother was pregnant at the age of fifteen!

Fifteen years old, only junior high school!

Thinking of this, Jiang Chen scolded again.

The person who compiled this teaching material is really a beast, so he should be arrested!

Mu Bai looked confused, and said strangely: "Can't you have children at the age of sixteen?" But I'm only two years old.

Jiang Chen: "..."The

beast is actually myself.

Scald!

After thinking about it, Jiang Chen still explained: "Under normal circumstances, human beings only start thinking about getting married and having children after the age of twenty.

Mu Bai's mouth opened slightly, and he was surprised: "So long? That... Then do I have to wait until I am twenty years old to be with Jiang Chen? "

Twenty years old! Eighteen more years!

For so long, kittens have become old cats!

Thinking like this, the corners of Mu Bai's mouth trembled, and he wanted to cry a little.

Jiang Chen smiled bitterly: "Not to need, according to the human situation, it is normal to fall in love around the age of sixteen." "

This wave, this wave, is called lifting a rock and shooting yourself in the foot.

"So I have to wait until I'm sixteen to be your girlfriend?" Mu Bai looked aggrieved, pitiful, and provoked pity.

Jiang Chen coughed lightly: "Mu Bai is different, your situation is very special."

Mu Bai wondered, "What's different?" I'm human too!

After thinking about it, Jiang Chen said, "Mu Bai, how old do you think you are now?"

"Hmm~eighteen?" Mu Bai said tentatively.

"On the outside, it's like this." Jiang Chen nodded.

"What about psychology?"

"I don't know, sometimes like eight, sometimes like eighteen, sometimes like twenty-eight." Jiang Chen said with a wry smile.

In fact, he felt that Mu Bai's mind was mature - as a cat.

It's just that because the time of human education is still too short, and the understanding of the world is still shallow, sometimes it still seems very naïve.

"So when can I be your girlfriend!" Mu Bai pouted and muttered.

Jiang Chen shook his head: "No hurry." Seeing

Jiang Chen's appearance, Mu Baiqi did not fight anywhere, hated his teeth, and muttered in a low voice.

"You're not in a hurry, I'm in a hurry!"

Jiang Chen smiled bitterly.

I'm in a hurry!

Who told you I'm not in a hurry!

But there is no way, Mu Bai has only been a human for more than a week, he really can't get his hands on it!

At least wait for someone to finish reading the high school knowledge, right?

"Study and study, let's look at this question..." Jiang Chen coughed lightly and said.

Mu Bai snorted lightly and muttered, "Stinky Jiang Chen!" Digression again! Every

time he talked about love, Jiang Chen avoided talking about it.

I really don't understand what he's worried about!

"Ahem, look at the question." Jiang Chen spoke, and then read the topic.

Mu Bai held his cheeks, unintentionally listening to the question, and looked at Jiang Chen's side face in a daze.

Jiang Chen's eyelashes are so long, and the side face is also good-looking.

It's a pity, a dumb.

I haven't said a word I like you in so long.

"Hey, this question is still relatively normal."

Jiang Chen finally saw a mathematical application problem that prevented him from myocardial infarction.

"There are nineteen passengers on a moving bus, and at each stop, five passengers go down, two passengers come up, and ask how many people are left on the bus after six stops."

Mu Bai returned to his senses and said stunnedly, "Jiang Chen, what did you just say?"

Helplessly, Jiang Chen could only read the question again and motioned for Mu Bai to read.

"It's not difficult."

Mu Bai picked up the paper and pen and wrote carefully.

Little Nizi made a bitter face while doing the question.

This question is still difficult for her.

After a long day, the answer was finally solved.

"Equal to 0.7!" Mu Bai said seriously.

Jiang Chen was speechless, and said helplessly: "Let's not talk about you not being a driver master, you tell me first, what does Zero Point Seven look like?!"

Mu Bai tilted his head and thought for a while, then muttered, "Then maybe the remaining person is a disabled person?"

Jiang Chen: "..."Mu

Bai is really a talent!

"Rewrite!" Jiang Chen said helplessly.

Mu Bai asked again: "Does the driver master also count?"

Jiang Chen had a black line: "The driver master is not a person!" "

Oh, then I won't, Jiang Chen, you teach me!"

"First of all, this question does not need to be formulated, you see..."
