Always get the Number 5 Trick
Have a pen or pencil and paper ready, or if you have to use a calculator.
Find a volunteer.

Get the volunteer to think of any three digit number. Eg 458

Add 7 to the chosen number.
458 + 7 = 465

Multiply the new number by 2.
465 x 2 = 930

Now Subtract 4 from that new number.
930 – 4 = 926

And now divide that new number by 2.
926 / 2 = 463

Subtract that new number with the number you started with
463 – 458 = 5
The answer will always be 5
Just like MAGIC 🙂
