Perhaps the most familiar example of subscripts is in [[chemical formula]]s. For example, the formula for [[glucose]] is [[Carbon|C]]<sub>6</sub>[[Hydrogen|H]]<sub>12</sub>[[Oxygen|O]]<sub>6</sub>, meaning that it is a molecule with 6 [[carbon]] atoms, 12 [[hydrogen]] atoms and six [[oxygen]] atoms. Subscripts are also used frequently in mathematics to define different versions of the same variable; for example, in an equation ''x''<sub>0</sub> and ''x''<sub>f</sub> may indicate the initial and final value of ''x'', while ''v''<sub>rocket</sub> and ''v''<sub>observer</sub> would stand for the velocities of a rocket and an observer. |

Perhaps the most familiar example of subscripts is in chemical formulas. For example, the formula for glucose is C6H12O6, meaning that it is a molecule with 6 carbon atoms, 12 hydrogen atoms and six oxygen atoms. Subscripts are also used frequently in mathematics to define different versions of the same variable; for example, in an equation x0 and xf may indicate the initial and final value of x, while vrocket and vobserver would stand for the velocities of a rocket and an observer.
