Why do you think adding and subtracting polynomial expressions is like adding and subtracting

Mathematics

Answer:

Polynomials are <em>closed</em> under addition and subtraction, which is fancy mathspeak that means that whenever we add or subtract two polynomials, we <em>always</em> get another polynomial. In that way, they behave a lot like the numbers you're probably already familiar with. Adding and subtracting:

  • Two integers gives you another integer
  • Two rational numbers gives you another rational number
  • Two real numbers gives you another real number

And it works the same with polynomials!
