    Wouldn't you just work your way out from the inside. 3-100=-97 2-(-97)=99 1-99=-98

    lets start from inside,, ............-(95 - (96 - (97 - ( 98 - ( 99 -100) ) ) ) ) ) ............-(95 - (96 -(97 - (98 - 99 + 100 ) .... ..........-(95 - (96 - (97 - 98 + 99 - 100 ).. .........-(95 - 96 + 97 - 98 + 99 - 100) sign alternates everytime for each no..i.e. 2 consecutive nos. have opposite signs.. in the end, we shall have 1- 2 +3 - 4 ......... -100 (1+3+5......99) - (2 +4 +6 ...100) 25(100 - 102) =-50 was that corretc ?
