Contrast linear growth with exponential growth, and gain an intuitive sense for massive numbers using powers of 10.
Comparing a ladder to the moon vs folding paper.
Imagine trying to build a ladder to the Moon, with a gap of 20 cm between each consecutive step.
Because the distance increases by a fixed, added amount with each step (additive growth), it would take an exhausting 1,92,20,00,000 steps (nearly 2 billion!) to reach the Moon.
