Exponential Notation

The idea
Exponential notation writes repeated multiplication compactly: the base is the factor, and the exponent counts how many times the base appears.
In practice
2⁵ means 2 · 2 · 2 · 2 · 2, which equals 32. Five appearances, one small raised number.
Where people slip
The exponent counts factors, not additions.
