Setting: A Math 10 class that has just been taught the concept of addition and subtraction of polynomials.
Mike: ”Mrs. M., come here. Do I have to change the signs in this one (polynomial)?”
(Mrs. M looks at the text and sees that the question reads “sum,” not “difference,” as this student is suggesting.)
