Introduction:

Mind tricks and puzzles have always fascinated people, as they provide not only an entertaining challenge but also an opportunity to sharpen our cognitive abilities. Number mind tricks, in particular, can be a great way to impress friends and family while exercising your mathematical prowess. In this article, we’ll explore three simple number mind tricks that you can master with minimal effort.

1. The 1089 Trick:

This famous number trick is surprisingly simple yet effective. To perform this trick, follow these steps:

a. Ask your friend to choose a three-digit number with decreasing digits (e.g., 732).

b. Reverse the digits of the chosen number and subtract the smaller number from the larger one (e.g., 732 – 237 = 495).

c. Reverse the digits of the resulting difference and add it to the original difference (e.g., 495 + 594 = 1089).
Voila! No matter which three-digit number your friend picks, you will always end up with the magic number of 1089.

2. The Age Trick:

Amaze your friends by accurately guessing their age using this simple arithmetic trick:

a. Ask your friend to multiply their age by 5.

b. Instruct them to add 3 to this product.

c. Then ask them to double the sum.

d. Finally, have them subtract their birth year (e.g., 1990) from the result.

When they reveal this final number, simply divide it by ten, and you will arrive at their current age!

3. The Day-of-the-Week Trick:
