FCCompareResults[{res1, res2, ...}, {res1Known, res2Known, ...}] compares the given list of expression {res1,res2,...} to the list of expressions {res1Known,res2Known,...} that represents the correct results. This is handy for checking both intermediate and final results of calculations, where you know what should come out at the end.
FCCompareResults[{4, 4}, {2^2, 8/2}]\text{Check of the results:} \;\text{The results agree.}
\text{True}
FCCompareResults[{3, 5}, {2^2, 8/2}]\text{Check of the results:} \;\text{The results disagree.}
\text{False}
