Interesting Math Stories

Children, do you know the story of the mathematical genius Gauss when he was a child?

When Gauss was in elementary school, one time after the teacher finished teaching addition, the teacher wanted to take a break, so he asked the students to do calculations. The topic was:

1 2 3 ..... 97 98 99 100 = ?

The teacher was thinking, now the children must be at 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 divide 10100 by 2 to get the answer equal to lt; 5050gt;

From then on, Gauss Elementary School The learning process has already surpassed other students, and also
