Question 11
The operator $\otimes$ acts on two integers to give the following outcomes: $$4\otimes8=818,\quad3\otimes6=616,$$ $$6\otimes12=1222,\quad10\otimes12=2022.$$ What is $20\otimes22$? Use the intended pattern: apply a fixed simple operation separately to each input, then concatenate the two decimal results. These examples are a pattern puzzle, not a unique definition on all integers.
