S = 1+2+3+4+5+6+7+8+.......
X = 1-1+1-1+1-1+1............
1-X = 1-1+1-1+1-1.......
1-X = X
2X = 1
X = 1/2
---------------------------------------
Y = 1-2+3-4+5-6..........
Y = +1-2+3-5+6..........
---------------------------
2Y = 1-1+1-1+1-1......
2Y =X
Y = X/2 = 1/4
-------------------------------------
S=1+2+3+4+5+6.....
S-Y = 1+2+3+4+5+6+....
-1+2-3+4-5+6+....
--------------------------------
S-Y = 0+4+0+8+0+12+.....
S-Y = 4(1+2+3+4..........)
S-Y = 4S
3S = -Y
S = -Y/3 = -1/12
1+2+3+4+5.................= -1/12
