  1. The addition of all the natural no. is?
    Its -1/8
    ok i know u r wondering how but lemme show u
    taking s = 1+2+3+4+5+6+7…………… on
    s = 1 +(2+3+4)+(5+6+7)+(8+9+10)+(11+12+13)…………….

    s = 1+ 9+18+27+36+45+54…………………..
    s = 1+9(1+2+3+4+5+6…….)
    now 1+2+3+4+5+6………………. = s
    s= 1+9s
    -8s = 1
    s=-1/8 like how?????????
