Let’s solve this step by step.
We are given a 2x2 grid:
```
2 5
1 6
```
And three clues:
a) It’s not 7 - 6
b) It’s not 10 - 8
c) It’s not 9 - 4
We need to figure out which number in the grid is the “secret number” — the one that
isn’t ruled out by these clues.

Step 1: Understand what the clues mean
Each clue says “It’s not [some subtraction]”. So we compute each subtraction:
- a) 7 - 6 =
1
- b) 10 - 8 =
2
- c) 9 - 4 =
5
So the clues are telling us:
> The secret number is NOT 1, NOT 2, and NOT 5.

Step 2: Look at the numbers in the grid
The grid contains:
2, 5, 1, 6
From the clues, we eliminate:
- 1 (from clue a)
- 2 (from clue b)
- 5 (from clue c)
That leaves only
6.

✔ Final Answer: 6
The secret number is
6, because it’s the only number in the grid that is *not* eliminated by any of the clues.

Bonus: Why is this called “Math Wizard”?
Because you have to do simple math (subtraction) to decode the clues, then use logic (elimination) to find the answer — like a wizard using math magic! 🧙♂️✨
