2. (8 points) There is a special calculator. When a number is input, the calculator first multiplies this number by 3, then reverses the digits of the result, and finally adds 2 to display the final result. Xiao Ming input a four-digit number, and the displayed result was 2015. What is the four-digit number that Xiao Ming input? $\qquad$ .

Xiao Ming input a four-digit number, and the displayed result was 2015. What was the four-digit number Xiao Ming input? $\qquad$ .

【Solution】Solution: According to the problem, the number went through the process of being multiplied by 3, then its digits were reversed, and finally 2 was added to get the number 2015. To find the original number, we can think in reverse.
$2015-2=2013$, then reverse it to get 3102, and divide by 3 to get $3102 \div 3=1034$.
Therefore, the answer is: 1034
