  When a torus acts on a compact oriented manifold with isolated fixed points,
the equivariant localization formula of Atiyah--Bott--Berline--Vergne converts
the integral of an equivariantly closed form to a finite sum over the fixed
points, providing a powerful tool for computing integrals on a manifold. This
article seeks to give an accessible exposition of the equivariant localization
formula.
