What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.
Its job in the formula
A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
The complexity dimension separates simulation sharply from the other two approaches. A simulation can, in principle, be run at essentially any scale the available compute allows: more grid points, finer time steps, more Monte Carlo samples, larger ensembles. Cost trades directly and continuously against precision. Neither peer review nor formal proof has that kind of dial. A human referee cannot review “80% as carefully” and get an 80%-as-reliable answer in linear proportion; below some threshold of attention, review quality can fail outright rather than gracefully degrading. A formal proof either typechecks or it does not — there is no partial credit inside the kernel, only degrees of how…
Learn the underlying idea
A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
