Number Tricks

Most of the time I get extremely excited when I see number tricks or facts I didn’t know before. A while ago, my reaction was: “why didn’t my maths teacher learn me that?!!”, but more recently I am saying: “Why didn’t I know about it?!”. Sometimes, I realize that even the maths teacher doesn’t know some of these, it just happens. But it is nice to find them, read about them, try them and then maybe share it with your maths teacher (if you are still in school), he/she might get really excited for it. So let’s get starting ^_^

1. Interesting multiplications: there are more tricks than the ones bellow, but these are some I have found and enjoyed recently.

2. Number patterns: it is quite fascinating to see that multiplication (also exponentiation) and addition can give rise to so nice patterns.

3. Numbers in different languages: this is something I have just recently discovered and I believe it is quite interesting. The way some numbers (especially big ones) are pronounced in different languages can give us some understanding of the properties of that number. Also, I believe it tells us something quite interesting about the culture of that specific country(ies) and the history of mathematics. The image above is just a small example, let me know how you pronounce those numbers in your mother tongue and if that tells us anything about those numbers.


Thank you for your help and support. You can find me onFacebook,  Tumblr,  Google+,  Twitter,  Instagram and Lettrs, I will try to post there as often as possible. Don’t forget that maths is everywhere! Enjoy!
