They are not. Counting numbers are a proper subset of whole numbers. Negative integers (-1, -2, -3 etc) are whole numbers but they are not counting numbers.
C. whole numbers can be negative and don't match the other sets
Each integer is a whole number and each whole number is an integer. So the set of all integers is the same as the set of all whole numbers. By the equivalence of sets, integers and whole numbers are the same.
The set of integers is the same as the set of whole numbers.
1 and 0 are the two whole numbers with their sum same as their difference
They are not. Counting numbers are a proper subset of whole numbers. Negative integers (-1, -2, -3 etc) are whole numbers but they are not counting numbers.
Apart from poor spelling, this question is based on a fallacy. Counting numbers and whole numbers are NOT the same. For example, -3 is a whole number but it is not a counting number.
Curiously enough, yes.For each non-zero counting number, N, there are two whole numbers, -N and N. And then there is zero. So the number of whole numbers is approximately double the number of counting numbers. However, the count of such numbers - the cardinality of both of the two sets - is "countably infinite" and the property of this infinite value is that multiplying it by any number still gives the same infinity!
You don't "count with fractions". Counting is done with natural numbers.
Counting numbers are a proper subset of whole numbers which are the same as integers which are a proper subset of rational numbers.
There are no whole numbers that are not also counting numbers. Both terms mean the same subset of numbers: positive integers greater than zero. Some people consider zero to be a whole number but not a counting number, because you can't "count" zero.
C. whole numbers can be negative and don't match the other sets
Counting numbers are positive integers 1, 2, 3 and so on. There is some disagreement whether natural numbers are the same thing or whether they include zero like whole numbers.
They are the same except that zero is included in the "whole numbers". Actually, not everyone agrees on that definition, but it's the usual one.
u cant
As long as you are counting in base 10 numbers, yes.
Yes. It must be at least one of the numbers on the list. If there is the same amount of each number, then there is no mode.
