Doubling is simply doubling, and quadrupling cannot be simply understood as quadrupling.
Quadrupling is expressed by a mathematical formula, which is a multiple of 2.
How many times is a number multiplied by the power of 2? For example, three times of 20 is 20 times of 2, and the formula is 20 * 2 3 = 20 * 8 = 160, which means that three times of 20 is160, which is eight times of the original, that is, the power of 2.
