 # Electric Charge
 - Charges come in two varieties, positive and negative.
 - Net charge is the *algebraic sum* of an object's charges
-- Protons and electrons have the same magnitude of charge ($1e$)
+- Protons and electrons have the same magnitude of charge (designated $1e$; a unit, **not** Euler's number)
 	- The SI Unit of charge is the *Coulomb* (abbreviated C)
 	- The smallest discrete quantity of charge is $\frac{1}{3}e$.
 - In an isolated system, the net charge will always remain constant.

 # The Superposition Principle
 The superposition principle states that:
-> The net charge acting on a point charge is equal to the sum of all individual forces.

+This means that to find the net force acting on a single charge, you add up all of the individual forces acting on that charge.
