%n or Out[n]
is a global object that is assigned to be the value produced on the n
output line.
%%
gives the result before last. %%…% (k times) gives the k
previous result.

%n or Out[n]
is a global object that is assigned to be the value produced on the n
output line.
%
gives the last result generated.
%%
gives the result before last. %%…% (k times) gives the k

A combinations of n % signs is equivalent to Out[-n]:

{Out[-1], Out[-2]} === {%, %%}Hold[%] === Hold[Out[]]Referencing an output number greater than the total number of outputs returns unevaluated:
Out[5]If $HistoryLength is finite, only the $HistoryLength most recent values of Out will have a value:
$HistoryLength = 2;
1 + 1;
2 + 2;
3 + 3;
