      Hi Max,
       
      As per the given conditions, you are not permitted to use any one sign more than once. therefore use of multiplication sign (*) twice in the equation is not allowed.
       
      good try but please think again.

      Hi,
       
      Here are my answer :
       
       
      20* 0.8 = 2* 8
       
      2*0.08 = .2* .8
       
       
      Thank you,
       
      Max

      Might look like cheating, but here are mine
      but here is mine

      (2 - 0 - 0 ) * 8 = 2 * 8
      (2 - 0) * ( 0 - 8) = 2 * (-8)
