what is the sum of 59 consecutive integers from - 29 inclusive , in a increasing order ?
"from - 29 to - 1 - - > 29 nos . zero - - > 1 number from + 1 to + 29 - - > 29 nos . when we add up nos . from - 29 to + 29 sum will be zero for total 59 nos . sum of these 59 nos . = 0 . d is the answer ."
add(29, const_1)
