this is not really a joke
but still very interesting :

13837 x (your age) x 73 =

make the multiplication (you can use a calculator)

so interesting!!

3. ## Re: the wonder of mathematics

hahah why does this happen? Anyone knows?

4. ## Re: the wonder of mathematics

Great, very interesting, I love math tricks like this.

For any 2-digit number, let's call it AB, if you multiply it by 1010101, you get ABABABAB.

This trick only works if your age is between 10 and 99.

6. ## Re: the wonder of mathematics

also for ages 1 to 9
so from 1 to 99 years of age
when you are 100 or older, you get one bonus year ! 7. ## Re: the wonder of mathematics

Yeah Frank, you are right, for an age 1 to 9 (let's call it A) you get A0A0A0A

I found one that works with 3-digit age

108911 x (your age) x 9191

I Love Math ^_^
