Math is wonderful if one could just understand it. Luckily, some people can, and some of them are even so nice as to give the rest of us a little insight into its aspects which are applicable in real life. Because, as unbelievable as it sounds, maths can be fun for mortals too. You don’t believe it? Check this out!

What if we told you there’s a way to find out the exact age of a person, by asking them six simple question. Based on a simple algorithm, you can now impress you friends with this cool trick.


Let us begin:

Pick a number between 1 and 9.

Instruction 1 – Multiply that selected number by 2.

Instruction 2 – Add 5.

Instruction 3 – Multiply that number by 50.

Instruction 4 – If you have already had your birthday this year, add 1763.

Instruction 5 – If you haven’t had a birthday this year, add 1762.

Instruction 6 – Subtract your sum with the 4 digit year you were born in.

The answer: The first digit is the number picked at the beginning. The next digit is your age!

An example with a person born in 1986

1. The number chosen was 5

2. 5×2=10

3. 10+5=15

4. 15×50=750

5. 750+1.766=2.516

6. 2.516-1.986=530

7. 5 was the selected number, and the person is 30 years old.
