The question:

So, what are you trying to figure out? The deceptively easyequation is

9=90

8=72

7=56

6=42

3=?

It appears to be a simple equation, straightforward addition,subtraction, and multiplication that we learn at a young age.But all is not as it seems.

ANSWER:
Each result seems to be calculated as:
nx(n+1)
Verifying this pattern:
9×10=90
8×9=72

7×8=56

6×7=42
Following the pattern for 3
3×4=12
So, the missing number is 12.
