Secret Code Math worksheet for comparing numbers using symbols.

It looks like you've uploaded a "Secret Code Math" worksheet where students must decode symbols into numbers and then compare them using the symbols <, >, or =.

Let's go through this step by step. First, we need to decode the symbols based on the key provided at the top of the page.

🔍 Step 1: Decode the Symbols

The key at the top shows:

```
1 2 3 4 5 6 7 8 9 0
X ∆ ∇ O ◄ ● J F G R
```

So each symbol represents a digit:

| Symbol | Number |
|--------|--------|
| X | 1 |
| ∆ | 2 |
| ∇ | 3 |
| O | 4 |
| ◄ | 5 |
| ● | 6 |
| J | 7 |
| F | 8 |
| G | 9 |
| R | 0 |

Now, let’s decode each pair of numbers in the problems and compare them.

We’ll go row by row.

🧮 Problem 1 (already done for us):

```
3 2 4 8 ⃝ 3 4 2 8
```

Decode:
- Left: 3 2 4 8 → ∇ ∆ O F → 3 2 4 8 → 3248
- Right: 3 4 2 8 → ∇ O ∆ F → 3 4 2 8 → 3428

Compare:
3248 < 3428 → So answer is <

✔ Already filled in as `<` — correct!

🧮 Problem 2:

```
X F G O ⃝ X F G O
```

Left: X F G O → 1 8 9 4 → 1894
Right: X F G O → 1 8 9 4 → 1894

Compare: 1894 = 1894 → Answer: =

✔ Fill in =

🧮 Problem 3:

```
● G F ← ⃝ ● G F ←
```

Wait — look at the symbols:
Left: ● G F ← → 6 9 8 5 → 6985
Right: ● G F ← → 6 9 8 5 → 6985

So again: 6985 = 6985 → =

✔ Fill in =

🧮 Problem 4:

```
∆ X ∆ O ⃝ ∆ X ∆ O
```

Left: ∆ X ∆ O → 2 1 2 4 → 2124
Right: ∆ X ∆ O → 2 1 2 4 → 2124

→ =

✔ Fill in =

🧮 Problem 5:

```
X ◄ O ● ⃝ ◄ X O ●
```

Left: X ◄ O ● → 1 5 4 6 → 1546
Right: ◄ X O ● → 5 1 4 6 → 5146

Compare: 1546 < 5146 → <

✔ Fill in <

🧮 Problem 6:

```
F G O ◄ ⃝ F G O ◄
```

Left: F G O ◄ → 8 9 4 5 → 8945
Right: F G O ◄ → 8 9 4 5 → 8945

→ =

✔ Fill in =

🧮 Problem 7:

```
J O G F ⃝ J O G F
```

Left: J O G F → 7 4 9 8 → 7498
Right: J O G F → 7 4 9 8 → 7498

→ =

✔ Fill in =

🧮 Problem 8:

```
O O O O ⃝ G F G O
```

Left: O O O O → 4 4 4 4 → 4444
Right: G F G O → 9 8 9 4 → 9894

Compare: 4444 < 9894 → <

✔ Fill in <

🧮 Problem 9:

```
∇ ◄ X ∆ ⃝ ∇ ◄ X ∆
```

Left: ∇ ◄ X ∆ → 3 5 1 2 → 3512
Right: ∇ ◄ X ∆ → 3 5 1 2 → 3512

→ =

✔ Fill in =

🧮 Problem 10:

```
X F G O ⃝ O X ∆ ◄
```

Left: X F G O → 1 8 9 4 → 1894
Right: O X ∆ ◄ → 4 1 2 5 → 4125

Compare: 1894 < 4125 → <

✔ Fill in <

🧮 Problem 11:

```
O O O O ⃝ F ← G ●
```

Left: O O O O → 4 4 4 4 → 4444
Right: F ← G ● → 8 5 9 6 → 8596

Compare: 4444 < 8596 → <

✔ Fill in <

🧮 Problem 12:

```
G ← ● O ⃝ F ← G ●
```

Left: G ← ● O → 9 5 6 4 → 9564
Right: F ← G ● → 8 5 9 6 → 8596

Compare: 9564 > 8596 → >

✔ Fill in >

✔ Final Answers:

Here are all the comparisons with their decoded values:

| Problem | Left Side | Right Side | Comparison |
|--------|-----------|------------|------------|
| 1 | 3248 | 3428 | < |
| 2 | 1894 | 1894 | = |
| 3 | 6985 | 6985 | = |
| 4 | 2124 | 2124 | = |
