No.
The answer below is incomplete.The set of whole numbers also includes all negative integers.
The set of positive integers does not contain the additive inverses of all but the identity. It is, therefore, not a group.
The "integers of 15" appear to be '1' and '5'. Their product is 5 .
The set of positive integers, of course!
All the numerals are integers (positive integers)
No. 0 is a non-negative integer which is not positive.
yes integers are all numbers negative and positive
No.
The sum of all positive integers in infinite. I am not sure how this particular idea is useful.
positive integers
The final result is positive.
The set of all positive integers is a subset of the set of all integers.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
At least the following families: all integers; all positive integers; all odd integers; and all "square integers", that is, integers that are squares of other integers.
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).
