Nominal Numbers: Nominal selection is utilised only as a name. It doesn't denote an actual price or the posture of some thing.
Transitive House: If x is equal to y and y is equal to z, then we can easily say that x = z. It's expressed as, x = y and y = z ⇒ x = z.

Most authentic numbers can only be approximated by decimal numerals, through which a decimal stage is put to the appropriate of the digit with put value one. Each individual digit to the right with the decimal issue has a location price 1-tenth from the place worth of the digit to its still left.
