Istandardised≈M+N.I_{\mathrm{standardised}} \approx M + N.
subscript

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

A protocol that both sides target once, instead, lets each side write a single adapter to the shared standard, so the count becomes Istandardised≈M+NI_{\mathrm{standardised}} \approx M + N. This is an illustrative accounting, not a verified cost function — real integrations are not uniform in effort, and a bespoke connector written once is not literally rebuilt M separate times in practice. What the two expressions capture correctly is the shape of the argument both LSP and MCP’s own announcement make: the saving claimed is structural, in how many distinct things must exist and be maintained, not a claim that any single connector becomes individually cheaper to write [ 5 , 6 ] .

A subscript is a label attached below a symbol. It often selects a time step, component, category, or member of a sequence.
