- All the multiples of 80 are numbers that can be divided by 80 without leaving a comma spot.
- It is not reasanoble to list all multiples of 80, because this list would be an infinite number of multiples of eighty. This is why we show the multiplication table to the first one hundred multiples of 80.

- 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 8.**The octahedron is one of the five platonic bodies. A polygon with eight sides is an octagon. In computer technology we use a number system on the basis of eight, the octal system. Eight is the first real cubic number, if one disregards 1 cube. It is also the smallest composed of three prime number. Every odd number greater than one, raised to the square, resulting in a multiple of eight with a remainder of one. The Eight is the smallest Leyland number.**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 eighty if it contains the number 80 a particular amount of times. 400 is a multiple of 80 because it contains number 80 five times.
- A number is a multiple of 80 when it is the result of multiplying 80 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.
