These riddles aren’t about how smart you are. They’re about how well you notice things.

Each one uses misdirection, subtle wordplay, or hidden meaning to throw you off. If you race through them, you’ll likely miss the trick. But if you slow down and really pay attention, you’ll catch what others miss.

1.

• Question: Use your brain. No calculator.
  5+5×5 x 0+1×5=?
  Answer: 10.
  Step 1: Handle all multiplications
  5 × 5 = 25
  25 × 0 = 0
  1 × 5 = 5
  That gives us: 5 + 0 + 5
  Step 2: Add
  5 + 0 + 5 = 10

• Question: A clock chimes once every second after the first strike. If it chimes 5 times for 5 o’clock, it takes 4 seconds. How long will it take to chime 10 times for 10 o’clock?
  Answer: 9 seconds.
  When a clock strikes an hour, there’s a pause between each strike. The total time is spent between the strikes, not during the strikes themselves.
  At 5 o’clock:
  5 strikes = 4 intervals
  4 intervals = 4 seconds
  So for 10 o’clock:
  10 strikes = 9 intervals
  9 intervals = 9 seconds
