Is the calulator broken ?? that is me being facetious.
-4.8-(4.9)+5.7 = -4
Technically, Melody......you answered on May 16th.......thus.....you are disqualified.....
I guess, BUT our guest asked me on the 16th so they wanted me to answer before the question was asked.
Maybe that is why the calculator was broken!! Maybe calcs don't cope well with time travel!
