For Cecil's new act, his tightrope is 5 feet long. If he begins at point A, write two expressions that will make him end at point B. What do these expressions have in common? Explain why 5+2+(−2) is equivalent to (the same as) telling Cecil to move 5 feet to the right. Will 5+2+(−2)+2+(−2) get Cecil to point B? Will 5+2+(−2)+3+(−3)? How would you describe his movements in these cases?
