Answer 30

how can it be Sum of odd number from 1 to 100? there is -3 not 3

Answer 31

1 -(2 -(3 -(.....100.....)
=1-2+(3-(...100...)
=1-2+3-(4-(5...100...)

Answer 32

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 ?
