Su Xiaoting ignored the little girl, what are you kidding, this is not a piece of five cents, it is a huge sum of a hundred yuan, how can she be willing to let the little girl play?

So she urged the stall owner: "You collect the money!" ”

The stall owner looked at Su Qinghe, and he took the money after Su Qinghe nodded.

"Looking for money!" As soon as the banknotes left her hand, Su Xiaoting said that she was afraid that the stall owner would not ask her for money.

Su Qinghe raised his eyebrows, "Tingting, do you know how much money I want to get back for you?" ”

As soon as the stall owner heard this, he knew that the parents were testing the child, so he stopped rummaging through his pocket to find change.

And the little obedient saw that the money she fancied was taken away by others, and she was so anxious that she screamed, Su Qinghe was waiting for Su Xiaoting to answer, and picked up a bubble machine and put it in the little obedient hand.

Seeing the cute shape of the bubble machine, the little guy stopped making a fuss and picked it with his fingers.

The stall owner is not worried that this little cute baby will break his bubble machine, after all, he still has a hundred yuan in his hand and has no change. On the contrary, he was more interested in this older little girl, could she be able to add and subtract within a hundred?

Su Xiaoting wrenched and wrenched her ten fingers, her little face was almost wrinkled, her lips rolled up and down, and it took a while for her to raise her head, her eyes shining, "I want to get back eighty-eight yuan!" ”

The stall owner's eyes widened, good guy, what the hell was I expecting?

"Are you sure?" Su Qinghe held back his laughter, he was usually used to seeing Su Xiaoting's sensible appearance, and thought that she could do anything, but this turned out to be a joke.

Su Xiaoting was very confident, "I'm sure!" ”

The stall owner complained: Are you sure you're a ghost!

"Tell me how you do that?" Su Qinghe was suddenly curious.

"One hundred minus twenty equals eighty, ten minus two equals eight, eighty plus eight equals eighty-eight!" Su Xiaoting wrenched her fingers, and said it reasonably, with a loud voice.

tomato

"No, why do you want eighty plus eight? Why is eighty added to eight? Why not eighty minus two? The stall owner was distraught and was broken by the arithmetic of a little girl who was almost seven years old and had just entered the first grade.

Su Xiaoting frowned deeply, "But why should I subtract two, twenty-two is twenty plus two, so I have to add it!" ”

"Then where did you get that ten minus two?" The stall owner is mad inside.

You say she won't, she'll split twenty-two into twenty plus two.

You said she would, she borrowed ten to minus two from eighty miles, but she didn't pay it back!

Su Xiaoting was stunned, "Yes, where did my ten come from?" ”

Quickly wrenched his fingers again.

The stall owner's red banknotes were put in his waist bag, and he quickly found the money and handed it to Su Xiaoting, with a serious face: "Classmate, I'm looking for you seventy-eight yuan, that's right, you go home and count it slowly." ”

Su Xiaoting hadn't straightened out her train of thought yet, so she took the money in a daze and looked at Su Qinghe with her head held high.

Su Qinghe nodded, "Seventy-eight is right, can you figure it out?" ”

Su Xiaoting grabbed her watermelon head irritably, "Did I miscount?" ”

"You can count if there are seventy-eight dollars." The stall owner complained while filling the bubble machine and the gift into a plastic bag.

"Oooh!" Su Xiaoting nodded, and didn't bother with how she miscalculated, since Uncle Qinghe said that seventy-eight was right, then it must be seventy-eight.

Although she miscalculated the count, she would not count the money wrongly, "Fifty plus twenty equals seventy, seventy plus five equals seventy-five, three pieces of one piece equals three pieces, five plus three equals eight, seventy-eight dollars is right!" ”

Su Qinghe nodded when he heard it, it seems that the addition within a hundred Su Xiaoting is still organized, but this non-integer subtraction is a bit of a mess.

"Sister, give you money!" Su Xiaoting took out a piece of money and held it in her hand.

It's just that the little girl now has a bubble machine, and she is having fun, and she doesn't like to play with money very much.

"This ......" the stall owner looked at the little obedient.

"I'll buy this too, how much does it cost?" Su Qinghe took out his mobile phone.

"This can be charged, it costs forty yuan, of course, there are many things to give."

"Just put the things in that bag, it doesn't matter if you put them together." Su Qinghe scanned the code and paid.

Seeing that Su Qinghe was so simple, the stall owner also sent more than ten packets of bubble liquid, and when he handed the bag to Su Xiaoting, he didn't forget to remind: "Little classmate, when you go back, you have to think about it, why you don't pay it back after borrowing ten!" ”

"What to borrow ten?" Su Xiaoting was stunned.

The stall owner didn't want to speak, so Su Qinghe smiled and pulled Su Xiaoting to find a place to sit down.

The negative floor of Wanze City is very lively, not only there are all kinds of food stalls and toy stalls, but also such as clothing stalls, cultural play stalls, fortune-telling stalls, etc., which are no different from the streets in the town.

"Tingting, who taught you to count?" Su Qinghe couldn't help but smile and asked, when he thought of Su Xiaoting's confident eighty-eight appearance just now, he wanted to laugh.

"I think that's how they all count." Su Xiaoting shook her feet, "How could I be wrong?" ”

Su Qinghe was stunned, "You mean you watched others count and learned it yourself?" ”

"That's right, I won't be cheated out of money if I learn to count! But how could I have miscalculated? Su Xiaoting was still puzzled by her miscalculation.

According to your calculations, not only will you not be cheated out of money, but you will also make money!

Su Qinghe sneered, and asked again: "Have you figured out where the ten minus two came from?" ”

Su Xiaoting shook her head, "Why did that uncle just say that I borrowed ten, I didn't borrow ten yuan from anyone!" I don't even borrow money from anyone! ”

Su Qinghe raised his forehead, "No, you borrowed, you borrowed ten yuan from eighty yuan!" ”

"Huh?" Su Xiaoting was surprised, "How can I borrow money from money?" ”

"Otherwise, where did you come from?"

"yes, where did this ten come from?"

Su Qinghe glanced at her obediently, she was still picking at the spit of the bubble machine, entertaining herself, while she was still not making trouble, Su Qinghe decided to have a good fight with Su Xiaoting.

"Twenty-two dollars for your bubble machine, right, you gave a hundred, according to your thinking, one hundred minus twenty equals eighty, right?"

"That's right!"

"Then there are two more pieces, do these two pieces have to be subtracted by eighty?"

"Huh?" Su Xiaoting asked, "Why is it eighty, not ten?" ”

Su Qinghe: ???

Why are you so entangled in this ten?

Doesn't make sense, does it?

Su Qinghe was weak, "Where did you come from?" ”

How did the topic come back to this "ten"?

Su Qinghe has nothing to love, he can expect that in the future, he will tutor and do his homework obediently.

Even now it's understandable why some parents can't help but lose their temper when tutoring their children with homework.

But if he is so smart, he shouldn't have high blood pressure that day, right?

Su Xiaoting thought for a long time, "I know where this ten came from!" ”

"Where?"

"That's how they all count!"

"Who are they?"

"Those adults in the village, and the old ...... lychee"

Su Qinghe understands that Su Xiaoting can do arithmetic, integer subtraction and single-digit subtraction are quite understandable, not to mention addition, but this non-integer subtraction, she only learned to split, and then she won't, so she relies on life to make it in vain.
