2. (10 points) From the 5 numbers $1,2,3,4,5$, select 4 different numbers to fill in the 4 squares below: $\square+\square>\square$ $\square$ $+\square$, there are $\qquad$ different ways to make the equation true. (Hint: $1+5>2+3$ and $5+1>2+3$ are considered different ways)

Fill in the blanks with the correct answers.
【Analysis】We can start by considering the first and last digits:
For combinations greater than $1+5$ (1 type), there is $3+4>1+5$
For combinations greater than $1+4$ (2 types), there are $2+5>1+4,3+5>1+4$
For combinations greater than $1+3$ (3 types), there are $2+4>1+3,2+5>1+3,4+5>1+3$
And so on, for combinations greater than $1+2$ there are 3 types
For combinations greater than $2+3$ there are 2 types
For combinations greater than $2+4$ there is 1 type
Each combination has 4 different ways to fill in, and the solution can be found accordingly.
【Solution】Solution: For combinations greater than $1+5$ (1 type), there is $3+4>1+5$
For combinations greater than $1+4$ (2 types), there are $2+5>1+4,3+5>1+4$
For combinations greater than $1+3$ (3 types), there are $2+4>1+3,2+5>1+3,4+5>1+3$
And so on, for combinations greater than $1+2$ there are 3 types
For combinations greater than $2+3$ there are 2 types
For combinations greater than $2+4$ there is 1 type
$$
\begin{aligned}
& (1+2+3) \times 2 \times 4 \\
= & 12 \times 4 \\
= & 48 \text { (types) }
\end{aligned}
$$

Answer: There are 48 different ways to fill in the blanks to make the equation true.
Therefore, the answer is: 48.
