Alright that's it, since people here can't read properly, I'm going to repeat myself here:
"OK fellas, or Indians specifically, seems like primary school hasn't taught you any maths correctly so I'm going to fill in for the 8X IQ people.
Take pi, and variables for example, they're there to FILL IN for a number. Pi=3.124... and variables, or unknowns, x, y etc. can STAND IN FOR ANY NUMBER.
Just because the Chinese didn't use 0 in PARTICULAR, doesn't mean we can't use another denotion for the meaning of NOTHING. 0 is nothing but a pre-designated numeral, not a meaning for NOTHING, because I can use MONKEY and I can still use that to DENOTE 0.
Happy 8X IQ fellas?
If you don't agree, then I'll use the following function (Simple parabolic curve) for example:
f(x)=x^2-2x+1
Here it comes-LET X BE 1, FIND f(1):
f(1)=0
Oh look, I just made X to be 1, and would it be OK if I adjusted my function slightly?
g(s)=s^2-2s+1, Oh look! Exactly the same? I can make s=1 to find my g(s) or y value now! See, it doesn't matter what variable I use, I can always make it stand in for the number I want.
QED-Quite Easily Done, or "the way to be shown" in Latin.
Thanks fellas!"
