Heureka’s interpretation and response is correct.
The double left less than << is a programming code meaning to shift the bits left, in this case, 16 times. (This is not the same as rotating the bits left). This effectively multiplies the registry value by 2, sixteen times.
$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{1}}{\mathtt{\,\small\textbf+\,}}{\mathtt{0}}{\mathtt{\,\times\,}}{\mathtt{16}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}}{\mathtt{\,\times\,}}{{\mathtt{16}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}}{\mathtt{\,\times\,}}{{\mathtt{16}}}^{{\mathtt{3}}} = {\mathtt{43\,522}}$$
0xaa02<<16
$$AA02_{16} = 43522_{10}\\\\
0\times aa02<<16 =
43522\cdot 2^{16} = 2~852~257~792$$
Radix and Heureka may have accurate imaginations but to me thie question is nonsense.
