Question

(-1)*(-1)*(-1)*(-1)*(-1) = ?

Answer 1

Answer: -1

Step-by-step explanation:

(-1)*(-1)*(-1)*(-1)*(-1)

= 1*1*(-1)                       [(-1)*(-1) = 1 and there are five (-1) so the first two together will be 1 and the third and fourth together will be 1, and the fifth    (-1) will remain as it is.]

= 1*(-1)          (1*1 = 1 and the (-1) will again remain as it is)

= -1               [1*(-1) = -1]
