Learning a lot of new things

I learn a lot of new things all the time most of them are discoveries after I discover them I ask my dad to see if it is true if it is not true then he explains why it is not if it is he explains why it is true and how I figured it out.Yesterday I asked my dad that: X/5 x 10/2=X. That was true he told me it was because 10=5x2. Then if you did 10/2 early it would be 5 so X/5x5=X then I realized I just made it to hard for my self.
