My future school bag

With the development of science and technology, even the schoolbags have undergone earth-shaking changes - from an ordinary school bag to a multi-functional small square bag with multiple functions...

My bag has no bag, just a small square, which is composed of six colors, which are: red. yellow. blue. green. green. Hey. Purple, it is very small, only 3 cubic meters in size, don't look at it smaller than other ordinary bags, but it can be used N times better than other bags, but also N times!

First of all, when I put things, although there is no bag, but just say: "Receive, my..." No matter how far you can get things in the bag, and don't look at it small, put no problem, how big, how big Can you collect everything, are you surprised? Oh, because the four-dimensional space is created in this bag, these things are placed in the four-dimensional space, not in the bag! Not only that, no matter how much I put in, it won't change the weight of the bag!

Then, if I am afraid that the bag will not be seen, then I can say to the bag: "Four dimensions, store it again!" It will "disappear", so that you are not afraid of being stolen, not afraid of losing it.

If I want to take something, what should I take? Of course, it is to use sound. "Ah!" Maybe you will yell: "This is impossible, you lied to me!" In fact, I did not lie to you, I just said: "Spit, my..." things will come out of the bag and Fly to me.

After that, when I need to restore the schoolbag, I just have to say it. For example: I have already let the schoolbag "disappear". What should I do now? Of course, just say, just say: "School bag, come out!" There will be six squares of different colors in the air, and then together become a small square that is - my school bag.

If the bag is broken, you can call it to automatically reply, and it only takes three seconds! This is not afraid that it will be broken.

Finally, if the assignment does not work, it can teach me, if: I don't know 9 multiplied by X equals 72, the code X is a few, I ask it: "9 times X is equal to 72, code X is a few?" It can be calculated in one second and replies: "Because 72 is divided by 9 equals 8, so the code X is 8." And when I am bored, I can talk to it!

Do you really want it? Don't worry, as long as you are willing to learn, it is not difficult to invent this thing. At the same time, Chairman Mao Zedong also said that there is no difficulty in the world, as long as Kenden climbs. Learning is not difficult, mainly because you are willing to learn. adhere to. Work hard. Not give up. Not afraid of setbacks, if you can do this, then learning is not a problem for you. When you learn a lot of things, it is a piece of cake to invent this thing!
