1+1+2+3*5
1-3/5+1/2-2/5
(-2/3)+1/2+4/5+(-1/2)+(-1/3)
[-2*1/4+(-1/2)3]*(-2*2/3)+(-1*2/3)2÷5/3
2^1/2 、3^1/3 和5^1/5

matlab 编程数组的数据如下:8 1 1 1 1 1 1 3 3 2 1 1 5 1 1 3 1 1 2 1 1 5 3 3 3 1 1 4 5 1 1 1 1 1 2 2 2 2 4 3 1 5 4 2 1 1 1 2 1 3 1 1 2 2 5 2 1 3 2 5 1 1 3 1 1 1 1 2 1 5 4 2 2 1 3 4 1 2 3 1 2 4 4 1 1 1 2 2 2 2 2 1 1 4 4 1 3 2 1 1 5 1 1 3 7 1 1

2(2x-1)-3(5x 1)2(2x-1)-3(5x+1)

放缩法证明1/3^2+1/5^2+1/7^2+.+1/(2n+1)^2
1+1/(1+2)+1/(1+2+3)+1/(1+2+3+4)+1/(1+2+3+4+5).+1/(1+2+3+4+5.+100)
