The change in the value of a quantity divided by the elapsed time.
What is Average Rate of Change
The numbers used for counting. That is, the numbers 1, 2, 3, 4, etc.
What are natural numbers?
Parts of an expression or series separated by + or – signs, or the parts of a sequence separated by commas.
What is a term?

What is Domain?
