"'''A'''" represents:

:[[Adenine]], which is a purine base in [[DNA]] and [[RNA]]; "A" pairs with [[thymine]] in DNA or [[uracil]] in RNA.

:Adenosine, which is the the [[nucleoside]] containing adenine as its base.

:[[Ampere]]s, a unit of electric current

{{lowercase}}
'''''e''''' is a useful [[mathematical]] constant which is a [[transcendental]] number approximately equal to 2.718281828459045 . ''e'' can be used in [[logarithm]]s as the base, called a [[natural logarithm]]. ''e'' is named for [[Swiss]] [[mathematician]] [[Leonhard Euler]], though he did not discover the constant.

It has some remarkable properties. For example:

:<math>\frac{d}{dx}e^x = e^x.</math>

(i.e. the exponetial function is an [[eigenfunction]] of the [[derivative]] operator, with [[eigenvalue]] 1).

==Formulae for ''e''==
*With [[limit]]s - <math>e=\lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x</math><br /><br />
*With [[infinite series]] - <math>e=\sum_{n=0}^{\infty}\frac{1}{n!}</math>
