An interesting story about mathematics:

When Gauss was in primary school, once after the teacher finished teaching addition, the teacher wanted to take a rest, so he asked the students to do a calculation. Let’s do the math. The question is: 1 2 3 ..... 97 98 99 100=?

The teacher was thinking, now the children must count until the end of get out of class!

Just when he was about to make an excuse to go out, he was stopped by Gauss! !

It turns out that Gauss has already calculated it. Children, do you know how he calculated it?

Gauss told everyone how he calculated it: add 1 to 100 and 100 to 1 in two rows, that is to say: 1 2 3 4 ..... 96 97 98 99 100

100 99 98 97 96 ..... 4 3 2 1=101 101 101 ..... 101 101 101 101*** There are one hundred 101s added, but the calculation is repeated Twice, so dividing 10100 by 2 to get the answer means that from then on, Gauss's learning process in elementary school has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius!
