class 6 Mathematics Textbook Chapter 10 question answer
If you begin at Floor +2 in the Building of Fun and press the ‘–’ button three times, the lift moves down three floors. The first press lowers you to Floor +1, the second press to Floor 0 (ground floor), and the third press to Floor –1, where the Toy Store is located. This action shows how negative integers represent downward movement, simplifying navigation between floors using a clear mathematical system.
