The "Add" is added to the distance prescription, so in your case the maximum power in the reading zone should be +2.50D.

Greetings, I am primarily Presbyopic & my prescription I OD & OS +0.5; add 2.00. I have progressive lenses & my question is about the reading strength of the lenses. Is it 0.5 + 2.00=2.5 diopters or just 2.00 diopters at the bottom of the lens. Thanks. Rich
