In the two screenshots (in german) you have the task explanation and an example. Understand that.

The task provided in the image involves finding a number that solves a given equation where symbols represent digits. Here is a breakdown of the problem and example given:

### Problem Overview:
- The equation consists of symbols, each symbol standing for a digit (0–9).
- There are different kinds of symbols, and the number of digits they represent depends on how many symbols are used.
    - **●** stands for a digit between 0 and 9.
    - **■** stands for two digits, from 10 to 99.
    - **▲** stands for three digits, from 100 to 999.
  
### Important Notes:
- Leading zeros are not used (i.e., "007" is simply "7").
- The same symbol always represents the same digit, and different symbols represent different digits. However, the equation must be solved by choosing appropriate digits for each symbol.
  
### Two Examples:
#### Example 1: 
Equation: **▲ · 2 = 2**

- You need to find what number **▲** represents.
- When **▲ = 1**, the equation becomes:
  \[
  1 \cdot 2 = 2
  \]
  This is a correct equation, so the answer for **▲** is **1**.

#### Example 2: 
Equation: **◆ + ◆ = ◼◆**

- You need to find what number **◆** represents.
- When **◆ = 0**, the equation could be:
  \[
  22 + 0 = 22 \quad \text{or} \quad 77 + 0 = 77
  \]
  This satisfies the equation, so **◆ = 0** is the correct solution.

### Questions to Consider:
1. How can you generalize the solution strategy for equations with multiple symbols?
2. What would happen if more symbols or operations are introduced into the equation?
3. How do different base systems affect solving equations of this kind?
4. Can this method be extended to solve polynomial equations with unknown coefficients?
5. How does the restriction of no leading zeros influence the possible answers?

### Tip:
Always start by identifying which symbols represent the simplest part of the equation, and substitute them first to simplify the equation step by step.

Which number solves the equation represented by symbols, with each symbol standing for a specific digit or number?
