  3. Negative numbers are defined as numbers less than 0. For any negative number (n 0), it is always true that n < p. For example, if we compare -2 and +3, we have: -2 < +3 Thus, negative numbers are always smaller than positive numbers. Click here for more: https://www.tiwariacademy.com/ncert-solRead more

  4. Starting from floor +3, each press of the – button decreases the floor number by 1. After 5 presses, the calculation is: Floor = +3 - 5 = -2 Thus, you will be at floor -2. Click here for more: https://www.tiwariacademy.com/ncert-solutions/class-6/maths/

    Starting from floor +3, each press of the – button decreases the floor number by 1. After 5 presses, the calculation is:
    Floor = +3 – 5 = -2

    Thus, you will be at floor -2.
