Arabic numerals were not invented by the Arabs, but originated in ancient India. They were later mastered and improved by the Arabs and spread to the West. These numbers are called Arabic numerals. Later, as rumors spread, all parts of the world recognized this statement.
Arabic numerals were gradually created by ancient Indians in production and practice.
In ancient India, city construction required design and planning, and sacrifices required calculation of the movements of the sun, moon, and stars. Thus, mathematical calculations were born. Around 3000 BC, the inhabitants of the Indus Valley were more advanced in their numbers and adopted decimal calculation methods.
Three customers came to a certain store and were eager to buy cakes to catch the train. The time limit could not exceed 16 minutes. Several chefs said there was nothing they could do, because it takes five minutes to cook both sides of a pancake. A pot can hold two pancakes at a time, so it would take 20 minutes to cook three pancakes. At this time, chef Lao Li came and said that it would only take 15 minutes to use your brain. Do you know how to brand it?

Subtraction
Mathematics
In class, the teacher said to a student
: "How come you can't even subtract
? For example,
for example,
you have ten apples at home,
You ate four.
How much is the result?
"The student
said in frustration: "The result is
Ten slaps on the butt!
The use of logic
A student asked Einstein what the use of logic was.
Einstein asked him:
“
Two people climbed out from the chimney
One’s face was covered with soot and the other was clean. Which one do you think? Should one take a shower?
”
“
Of course
it’s the
dirty one.
”
The student said.
“
That’s not right. The dirty one sees that the other person is clean and thinks that he will not be dirty either.
Where can he take a shower?
”
Brain teaser:
One day, when the digital cards were having lunch together,
My younger brother said:

“
Let me
here, let’s take some photos together. What do you think?
”
The brothers and sisters all
said in unison:
“
Okay.

My brother said:
“0
My brother’s idea is really good, I am old

Supply cameras and film,
Okay?

said:
"
Okay Yes, it's just too troublesome, so I might as well use my digital camera.
That's it.
”
So they got busy, and finally the
+
number helped them take pictures, and immediately put the digital< /p>
The camera was sent to the store to have the photos developed,
the photos were developed,
the computer sister asked them for money,
but what did they do? Who pays?
They looked at each other blankly. This is the computer sister saying:
One ***

Yuan, you have ten yuan
How many yuan does each brother and sister pay on average?

Qiu Chengtong said:
“
After modern high-energy physics reaches quantum physics, there are many experiments that cannot be done at all.
At home, paper and pen are used to calculate.
This is different from mathematics. It’s not that far off from what everyone thinks,
So mathematics has incredible power in physics

The teacher was thinking, now the children must be at the end of get out of class! Just as he was about to make an excuse to go out, he was stopped by Gao Si!
!
It turns out,
Gauss has already calculated it.
Children, do you know how he calculated it? Gauss
He told everyone how he calculated it:
Add

Make two Row addition,
That is to say:
1+2+3+4+ ..... +96+97+98+99+100=101+101+ 101+ .....
+101+101+101+101
***There are one hundred

From then on, the learning process of Gauss Elementary School has already surpassed
other students, and made him become
