Claire asks Andre to play the following number puzzle:
- Pick a number
- Add 2
- Multiple by 3
- Subtract 7
- Add your original number
Andres final result is 26
Which number did he start with?
To determine the number Andre started with, we can work backwards through the given operations.
Andre's final result is 26. Let's reverse each step:
1. Add your original number: 26 + 7 = 33
2. Subtract 7: 33 - 7 = 26
3. Multiply by 3: 26/3 = 19
4. Add 2: 19 - 2 = 17
Therefore, the number Andre started with is 17.
