十九世纪德国大数学家高斯,早在七、八岁上小学时,就表现出非凡的才智.一次老师板演了一道计算题:计算1+2+3+……+100之和.当时许多同学算了半天也得不出正确答案,小高斯却很快把答案写在黑板上,老师问他是怎么得出来的?小高斯不加思索的说:把这100个数分成两组,1-50和51-100,它们两组头尾两数合为一对,其和都是101, In the nineteenth-century German mathematician Goss, as early as seven or eight years old, he showed extraordinary talents. A teacher played a calculation: calculating the sum of 1+2+3+......+100. Many students had no correct answer for a long time. Small Gauss quickly wrote the answer on the blackboard. The teacher asked him how he got it. Small Gauss said without thought: Divide the 100 numbers into two groups. 1-50 and 51-100, both of which have two pairs of heads and tails. The sum is 101.
