Question
If 2+3=10, 7+2=63, 6+5=66, then 8+4=?
Solution
This is a trick math puzzle where the plus sign (+) actually represents a compound operation: A + B = A * (A + B).
- 2 + 3 = 2 * (2 + 3) = 2 * 5 = 10
- 7 + 2 = 7 * (7 + 2) = 7 * 9 = 63
- 6 + 5 = 6 * (6 + 5) = 6 * 11 = 66
Following this pattern for the final equation:
8 + 4 = 8 * (8 + 4) = 8 * 12 = 96.
The answer is 96.

PRO TIP
The calculation isn't standard addition. Multiply the first number (A) by the sum of both numbers (A+B). (A * (A+B)).
