Glancing at the candy with a proud face, Mo Jingchun picked up "Math Olympiad" and opened a page.
1. My elder brother is 18 years old and my younger brother is 12 years old. If the sum of their ages is 40, how old are each brother?
2. A, B, and C each have several story books. A gives part of his books to B and C. For example, B and C have doubled their books. B gives part of his books to A and C. The books of A and C are doubled, and C also gives some books to A and B, so that the books of A and B are also doubled. At this time, the books of A, B, and C are all 16 Book. How many storybooks do A, B, and C originally own?
3. There is a bucket filled with 8 kilograms of water. If the bucket of water is divided equally into two buckets, the two buckets can hold 5 kilograms and 3 kilograms respectively. What is the minimum number of pours required?
That's it...that's it? ? ?
Mo Jingchun showed a surprised expression. But when I turned around and thought about it, I realized there was nothing wrong with it.
Some questions that are very simple in the eyes of senior high school students are actually difficult problems for junior high school students.
Not to mention a scientist like Mo Jingchun who is good at math.
Thinking of this, Mo Jingchun thought of Wang Haoran again.
These topics may not arouse the slightest interest in Wang Haoran's eyes.
For Wang Haoran, who has unparalleled talent in mathematics, if he has time to do Mathematical Olympiad questions, it is better to learn more knowledge.
Throwing the "Math Olympiad" on the desk, Mo Jingchun curled his lips and said, "There shouldn't be many questions in it that can stump you. If there are any problems, you will ask your class teacher."
The teacher resources in July 1st are definitely the best in the entire grade group.
Among them, there are two special teachers, which is evident from this.
"Why are you doing these questions when you have nothing to do? Listen to me, it's not of much use. People like us who are engaged in scientific research are not very interested in Mathematical Olympiads. But when you get to university, you can participate in the National College Student Mathematical Modeling Competition."
Candy, who had regained the Mathematical Olympiad, rolled her eyes at her brother in dissatisfaction.
"Brother, of course we are fighting for honor. Xiang'er and I are ready to take the top two spots in the Mathematical Olympiad."
Hearing this, Mo Jingchun raised his brows and said, "Don't be happy so early. I admit that you and Xiang'er are capable, but the more proud you are, the more you will get the worst results. Sometimes, the questions are more like word games.
It's like dividing and dividing by. One word difference, but a world of difference.
For those who happen to be learning this knowledge, they may be able to see it at a glance. But for people who have more knowledge, it is often easier to ignore such small problems.
It may even make you doubt yourself, the difference between dividing and dividing by, which one is the dividend. "
The candy was a little confused after being bombarded by Mo Jingchun.
What frightened Candy the most was that when her brother said this, she really confused the difference between division and division.
Looking at the confused Candy, Mo Jingchun raised the corners of his mouth slightly and used Wang Zha again.
"Classmate Mo Xiaoxue, remember to hand over half of the Mathematical Olympiad winning prize."
"impossible!"
Candy, who woke up instantly, took a step back and looked at his brother warily.
Candy really couldn't figure out why. His brother knew that there would be prize money in the Mathematical Olympiad competition.
Could it be that the head teacher told my brother? It's very possible. After all, you have to leave school to participate in the competition, so it's impossible for the head teacher not to tell your brother.
After figuring it out, Candy felt a little itchy.
"Ahem, as your first guardian, theoretically, I have to keep all the funds for you. However, I only want half. Where can you find a better brother than me?"
"Thank you~"
"Turn in half or all, you choose, or I'll call your class teacher and tell you that you are not allowed to participate in the competition.
Oh, by the way, a few days ago I just had the idea to discuss with someone’s class teacher whether to do homework, let’s see now...”
Mo Jingchun deliberately prolonged his tone, making Candy's eyes widen.
"Brother! I'm convinced! As agreed, the remaining half of the right to use it belongs to me! If you make any more decisions, I will be angry.
There is also the matter of after-school homework. Those homework are really just a waste of time for me. When writing homework, it is better to read more advanced mathematics books. "
"No problem!" Mo Jingchun readily agreed.
Withholding too much is not Mo Jingchun's style of doing things.
Of course, the most important thing is that Candy has been saving money but not spending it randomly. Mo Jingchun saw it all.
Especially the last time Candy took the initiative to enter a gold store and bought a set of sterling silver chopsticks and bowls for Zhou Yaling's baby, which surprised Mo Jingchun.
When paying, Candy didn't even blink, without any hesitation.
A few days later, with Mo Jingchun's permission, more than a dozen real experts and professors came to the controllable nuclear fusion experimental base whose security level had been upgraded again and again.
Looking at the controllable nuclear fusion device in front of them, they felt a little unreal.
While various countries around the world are still researching thermonuclear fusion and have just achieved some results, Candy Technology has quietly developed a cold controllable nuclear fusion reaction device.
The clock on the big screen not far away is counting continuously.
7 days, 16 hours, 23 minutes and 56 seconds
The straightforward numbers tell everyone that the cold fusion reactor in front of them has been working stably for 7 days, 16 hours, 23 minutes and 56 seconds.
Compared with the stable operation time of the small sun in their scientific research institute, this number is so dazzling.
Although I hate to admit it, fate always takes special care of geniuses.
On the premise of getting started with all the instruments and equipment, more than a dozen experts were finally invited out after watching for more than an hour.
"Dear professors, when Academician Mo left, he specifically stated that there may be certain dangers during the experiment. For your safety, please watch via remote video."
Facing more than a dozen experts and professors in front of him, Major Chen had a headache.
According to regulations, the on-site visit is one hour, but now it has obviously exceeded the time limit.
If Academician Mo takes a closer look, no one will feel uncomfortable.
"Ahem, let's not embarrass this young man. It's almost done. Let's go out and discuss our own ideas."
"Hahaha, okay."
The base was closed again, and Major Chen finally breathed a sigh of relief.
Compared with before, every step of the way and one sentry post here, the safety level has been raised to the highest level.
The purpose is to ensure that the cold controllable nuclear fusion reaction continues.
However, God seems to have deliberately made a joke on everyone.
Just as more than a dozen experts and professors were discussing, a roaring sound came from far and near.
The sound like thunder made everyone subconsciously raise their heads and look towards the south.
When everyone was still confused, one by one Baymax suddenly rushed out of the base, and kept playing the alarm.
"Alert, a 3.6-magnitude earthquake wave will arrive in 5 seconds."
