What this part means

Its job in the formula

Add the term after the plus sign to the term or group before it.

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 ] .

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
