    Prediction: Your result will be 18

    Think of a number.

    Add 7 to it.

    Subtract 2.

    Subtract your original number.

    Multiply by 4.

    Subtract 2.

    Explanation:

    This problem gives the illusion of guessing an unknown number, but the unknown has been cancelled mathematically.

    ( X + 7 – 2 – X ) × 4 – 2 = 18
