Since childhood, we were drawing things without knowing what we were drawing, like buildings, ships, planes, flags...etc
At first, we were thinking that mathematics was geometry, numbers, operations, relations and functions, but when we started the university, we found that mathematics is a field itself, where you can find different things and branches, e.g. our known algebra was divided into pure algebra and pure calculus. Also, geometry was divided into Euclidean space "n-dimensions" and differential geometry and some others.
On the other hand, there was many things that we were having fun when reading or seeing it in our text books or while searching for information on the Web. Things made us think deeply about its contents; one of these things were the numerical tricks. One of these things is the multiplication table of 9, which most students see it the most difficult one.
Other than this one, you can get the multiplication table of 9 using the ten fingers of your hand, and here the video for it in case you want to teach it to your kids.
And here are the multiplication tables for 6, 7, 8, 9 and 10 multiplied by themselves using both your hands.
Hope you have fun reading and trying the things in the videos..
Still I don't think math is fun >_<
