Mayan Math Worksheet for learning ancient number system with symbols and basic operations.

Let's solve the Mayan Math worksheet step by step. The Mayan number system is a vigesimal (base-20) system, but for this worksheet, we're only dealing with numbers from 0 to 19, using:

- Shell (○) = 0
- Dot (•) = 1
- Bar (—) = 5

Numbers are built by combining dots and bars vertically, where:
- Each bar = 5
- Each dot = 1
- Dots above or below bars add to the total
- The maximum in a single position is 19 (3 bars = 15, plus 4 dots = 19)

Part 1: Fill in missing Mayan symbols (0–19)

We’re given some examples. Let’s fill in the blanks.

| Number | Mayan Symbol |
|--------|--------------|
| 0 | Shell (○) |
| 1 | • |
| 2 | •• |
| 3 | ••• |
| 4 | •••• |
| 5 | — |
| 6 | —• |
| 7 | —•• |
| 8 | —••• |
| 9 | —•••• |
|10 | == |
|11 | ==• |
|12 | ==•• |
|13 | ==••• |
|14 | ==•••• |
|15 | === |
|16 | ===• |
|17 | ===•• |
|18 | ===••• |
|19 | ===•••• |

So the missing ones are:
- 2: ••
- 4: ••••
- 6: —•
- 7: —••
- 8: —•••
- 9: —••••
- 11: ==•
- 13: ==•••
- 14: ==••••
- 15: ===
- 17: ===••
- 18: ===•••

But since the worksheet already shows most of them, we’ll focus on Part 2 — solving the math problems.

Part 2: Solve the math problems using Mayan numbers

We need to compute each expression and write the answer in Mayan numerals.

---

#### Problem 1:
```
••
+ •••
-----
```

- Top: •• = 2
- Bottom: ••• = 3
- Sum: 2 + 3 = 5

Mayan symbol for 5: `—` (one bar)

✔ Answer: —

---

#### Problem 2:
```
••••
===
- ••
==
-----
```

Break it down:
- Top: •••• (4 dots) + === (3 bars = 15) → 4 + 15 = 19
- Bottom: •• (2 dots) + == (2 bars = 10) → 2 + 10 = 12
- Subtract: 19 - 12 = 7

Mayan symbol for 7: one bar (5) + two dots → `—••`

✔ Answer: —••

---

#### Problem 3:
```
•••
+ ••
==
+ ○
- —
-----
```

Step-by-step:
- First term: ••• = 3
- Second: •• = 2 → 3 + 2 = 5
- Third: == = 10 → 5 + 10 = 15
- Fourth: ○ = 0 → 15 + 0 = 15
- Fifth: — = 5 → 15 - 5 = 10

Mayan symbol for 10: two bars → `==`

✔ Answer: ==

---

#### Problem 4:
```
••
+ ••
- ••••
-----
```

- Top: •• = 2
- Middle: •• = 2 → 2 + 2 = 4
- Subtract: 4 - 4 = 0

Mayan symbol for 0: shell (○)

✔ Answer: ○

---

✔ Final Answers:

1. —
2. —••
3. ==
4. ○

---

Summary of Mayan Symbols Used:

| Number | Mayan Symbol |
|--------|--------------|
| 0 | ○ (shell) |
| 5 | — (bar) |
| 7 | —•• |
| 10 | == |
| 19 | ===•••• |

These answers should be written in the blank spaces on the worksheet using the correct Mayan symbols.
