1. (8 points) Define a new operation $a \preccurlyeq b$ such that: $a \preccurlyeq b=b \times 10+a \times 2$, then 2011 approx $130=$
【Solution】Solution: According to the analysis, 2011\$130
$$
\begin{array}{l}
=130 \times 10+2011 \times 2 \\
=1300+4022 \\
=5322
\end{array}
$$

Therefore, the answer is: 5322.
