Question

What is the least number of numbers you must list to have examples of all four sets of numbers, including at least one positive integer and one negative integer? Explain.

pls im desperate

Answer 1

I’m pretty sure it’s -1,0,1, because we are including integers (infinite number set), while numbers, and natural counting numbers.

Explanation on counting number sets:

Integers: integers are counting numbers that have positive numbers, their opposites, and 0 for example it could be -1,0,1 because we have a positive number (1), it’s opposite, (-1) and 0

Whole numbers: basically they just start at 0 example, 0,1,2,3

Natural counting numbers they skip the zero and start at one. They are called natural counting numbers because when we are counting stuff, we typically start at one instead of 0 like for example counting money. We wouldn’t go 0 dollars, 1 dollar. We would start at 1 if that makes sense. An example of this number set would be 1,2,3,4.

Thank you! I hope I helped you understand!!
