- All the multiples of 20 are numbers that can be divided by 20 without leaving a comma spot.
- It is not reasanoble to list all multiples of 20, because this list would be an infinite number of multiples of twenty. This is why we show the multiplication table to the first one hundred multiples of 20.

- In mathematics, a multiple is the product of any quantity and an integer. In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier or coefficient. If a is not zero, this is equivalent to saying that b/a is an integer with no remainder. If a and b are both integers, and b is a multiple of a, then a is called a divisor of b.
- 14, 49, -21 and 0 are multiples of 7, whereas 3 and -6 are not. This is because there are integers that 7 may be multiplied by to reach the values of 14, 49, 0 and -21, while there are no such integers for 3 and -6.

**About Number 2.**Two is the smallest and the only even prime number. Also it's the only prime which is followed by another prime number three. All even numbers are divisible by 2. Two is the third number of the Fibonacci sequence. Gottfried Wilhelm Leibniz discovered the dual system (binary or binary system) that uses only two digits to represent numbers. It witnessed the development of digital technology for a proliferation. Because of this, it is the best known and most important number system in addition to the commonly used decimal system.**About Number 0.**The number zero is the number of elements in an empty collection of objects, mathematically speaking, the cardinality of the empty set. Zero in mathematics by depending on the context variously defined objects, but often can be identified with each other, that is considered to be the same object, which combines several properties compatible with each other. As cardinal numbers (number of elements in a set) are identified with special ordinals, and the zero is just the smallest cardinal number is zero - elected as the first ordinal - in contrast to common parlance. As finite cardinal and ordinal it is depending on the definition often counted among the natural numbers. The zero is the identity element for addition in many bodies, such as the rational numbers, real numbers and complex numbers, and a common name for a neutral element in many algebraic structures, even if other elements are not identified with common numbers. Zero is the only real number that is neither positive nor negative.

- A number is multiple of twenty if it contains the number 20 a particular amount of times. 100 is a multiple of 20 because it contains number 20 five times.
- A number is a multiple of 20 when it is the result of multiplying 20 by another number.
- Properties: 0 is a multiple of everything (0=0*b). The product of any integer n and any integer is a multiple of n. In particular, n, which is equal to n * 1, is a multiple of n (every integer is a multiple of itself), since 1 is an integer. If a and b are multiples of x then a+b and a-b are also multiples of x.
