Numeral system is a writing system for expressing numbers.which is a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. Remainder theorem: Let p(x) be any polynomial of degree greater than or equal to one and let a be any real number. If p(x) is divided by the linear polynomial x – a, then the remainder is p(a).
Units digit of a number is the digit in the one's place of the number. i.e It is the rightmost digit of the number. The concept of unit digit can be learned by figuring out the unit digits of all the single digit numbers from 0 - 9 when raised to certain powers.
A non-terminating, non-repeating decimal is a decimal number that continues endlessly, with no group of digits repeating endlessly.
An irrational number-
An irrational number is a number that cannot be expressed as a fraction for any integers and. . Irrational numbers have decimal expansions that neither terminate nor become periodic. Every transcendental number is irrational.
Rational number-
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
Divisibility rules help us work out whether a number is exactly divisible by other numbers (i.e. there is no remainder).
Prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
