What is the little number below the big number?
Subscripts have many scientific applications, including mathematics, computer science, and chemistry.
The small “n” is a subscript.
When used in the context “Fn,” it refers to a function evaluated for the value “n.” The text n-1 and n-2 are also subscripts that define previous values of “n” in the sequence..

The Hill system (or Hill notation) is a system of writing empirical chemical formulae, molecular chemical formulae and components of a condensed formula such that the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements …
Is OH 2 the same as h2o?
Since there is one Hydrogen and two Oxygen atoms to form a water molecule. We write H2O. OH 2 means nothing. Because 2 hydrogen bonds are present in that bond and both are attached.
How do you type a small 2?
Hold down Alt and key in 0178 and let go of Alt. A superscript 2 will appear. Incidentally, if you needed ‘cubed’ instead of ‘squared’ then type 0179 and you’ll get a superscript 3. In fact, this will work anywhere in Windows or online – even in Word.
What does a subscript tell you in math?
