Subscript

Real World Example

Imagine you're trying to bake cookies and need to know how many cups of sugar to use for each batch. Just as the recipe tells you the exact amount of sugar needed for each set of cookies, a subscript in a chemical formula indicates the number of atoms of an element in a molecule. In both cases, the number is crucial: the recipe's measurement ensures the right sweetness, while the subscript ensures the correct composition of the molecule.
