Absolute rational number(Q)

These are those numbers which can be represented as p/q in which p and q ϵ N and q ≠0.

 Absolute Term

Any term that contants no unknown quantity in it.
Ex: In the equation ,  ax³+bx²+cx+d=0 , 'd' is the absolute term.

 Absolute Units

Those derived from the fundamental units of a system and not based on arbitrary numerical definitions.
