Hello!
All math operators I know is: add, sub and dis. Does FASM has math operators like cos, sqr, etc.. Or do I need to crate them by myself? Thank you!

I think you REALLY SHOULD learn some assembly!

...but I'm willing to help you on this:
x86 has ADD, ADC, SUB, SBB, INC, DEC, AAA, AAD, AAM, AAS, DAA, DAS in
its set. It also has some more complex instructions like XCGH, NEG, ADD
and MUL, IMUL, DIV, IDIV. (XADD beginning from 486)
There are exotics like XLAT and others user rarely.
So much for the integer part.
Floating point unit has A LOT OF math operations and YES FSIN, FCOS, FSQRT
are part of them. I won't list them here, because of the length of the list.
