Let a_{1 , }a_{2}, ……., a_{100} be non zero real number such that

a_{1} + a_{2} + …… + a_{100} = 0 then

a. ∑^{100}_{i=1 } a_{t } 2^{ai } > 0 and ∑^{100}_{i=1} a_{i }2^{-ai }<0

b. ∑^{100}_{i=1 } a_{t } 2^{ai } >= 0 and ∑^{100}_{i=1} a_{i }2^{-ai }>=0

c. ∑^{100}_{i=1 } a_{t } 2^{ai } <= 0 and ∑^{100}_{i=1} a_{i }2^{-ai }<=0

d. the sign of ∑^{100}_{i=1 } a_{t } 2^{ai} or ∑^{100}_{i=1 } a_{t } 2^{ai} depends on the choice of a_{i}’s
