draw a symbol to write a Maya number between 50 and 90

In the Maya numeral system, numbers are written using a combination of three symbols:
1. **Dot** (•) for 1 unit.
2. **Bar** (—) for 5 units.
3. **Shell** symbol (🌓 or similar) for 0.

To write a Maya number between **50 and 90**, you will use both bars and dots arranged in two layers, since the Maya system is vigesimal (base-20). Let's break it down:

For example, the number **65**:
- Top layer: The number of **twenties**, which is 3 (since \(65 = 3 \times 20 + 5\)). This is written as three dots.
- Bottom layer: The remainder, which is 5. This is written as a single bar.

Here’s what the **Maya number 65** looks like:
```

```
Three dots on the top for 60, and one bar on the bottom for 5, making 65.
