Counting objects into the chosen space symbolizes addition, while counting objects out of the space symbolizes subtraction.
Why is counting important in math?
Counting numbers helps build the concept of counting, as they are used to name the number in a set of objects. They allow us to quantitatively specify how many cars there are in a parking lot , the number of oranges in the refrigerator, etc. It therefore makes sense that negative numbers, fractions, and decimals are not included, since counting numbers assume that the objects being counted are whole (cannot be divided into smaller parts). We also can't count objects that don't exist, so it makes sense that 0 is also typically not included in the counting numbers.
