Brain Test Level 249
Question: Make the equation 15 + 15 = 15 correct.
This puzzle requires creative manipulation of the numbers and operators.
Solution:
You need to transform the result 15 into 30 using the elements available.
- Tap and drag the vertical line of the plus sign (+).
- Place this vertical line over the digit 5 in the result '15'. This transformation makes the 5 look like a 0.
- Now, tap and drag the remaining horizontal line of the plus sign.
- Place this horizontal line over the digit 1 in the result (now '10'). This transformation makes the 1 look like a 3.
- The equation now correctly reads 15 + 15 = 30.
