addition

What this part means

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

Its job in the formula

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

The passage around this formula

read in full every step for every active request. Total bytes moved per step across a batch of b requests at sequence length s is therefore approximately B(b,s)≈Np+b Mkv(s)B(b,s) \approx Np + b\,M_{\mathrm{kv}}(s). and the achievable step rate is B divided into the device’s usable bandwidth. Two things follow immediately.
