There are infinite number of negative non integers that have a product of 20. Any two negative fractions can make a product of 20. e.g.
-3/20 * -800/6 = 20
-3/8 * -320/6 = 20
-9/7 * -140/9 = 20
The list is endless. Only make sure you select both negative fractions to get a positive 20 and when selecting the fractions the numerator of one number is divisible by the other number's denominator such that the factors cancel to give 20.
The sign of the product of four integers depends on the signs of the individual integers. There are 4 cases: 1) When all 4 integers share the same sign and all are non-zero (either all are positive or all are negative), the product is positive. 2) When 3 of the 4 integers share the same sign and all are non-zero (3 are positive and 1 is negative; or 3 are negative and 1 is positive), the product is negative. 3) When 2 of the integers are positive non-zero and the other 2 of the integers are negative non-zero, the product is positive. 4) If even one of the integers is zero, the product is zero (no sign - it is neither positive nor negative).
An integer is either positive (non-negative), or negative, or zero. There are no negative non-negative integers.
Non-positive integers are zero and the negative integers.
Yes, the intersection of non-negative (positive) and non-positive (negative) integers is zero.
No. 0 is a non-negative integer which is not positive.
Unfortunately, in accordance with math laws, non real, negative integers cannot be factored."Prime numbers are defined as all real, non negative integers who's only factors are that of "1" and itself. Composite numbers are defined as all real, non negative integers who's factors are all real, non negative integers other than "1" and itself.
positive integers
all number can be negative or positive. :) The term "whole numbers" is ambiguous; sometimes it is used for integers, sometimes only for non-negative integers. It is better to use the more precise terms "integers", "positive integers", "non-negative integers", depending on what you want to say. it is also false if your looking for this answer caue it could be like 0.3,0.5 there not whole numbers
2/5 or 40%.
It is a universal set
Positive integers
They are all non-negative integers.
