Where countless little numbers surrender their identities to become one larger truth.
means The total you get when you add numbers together, or more loosely the whole amount of something.
from From Latin 'summa,' meaning 'the highest' or 'the top'—the feminine of 'summus,' superlative of 'superus,' 'higher.' The link is delightfully physical: Romans added columns of figures from the bottom up, so the final total sat at the TOP of the column. The 'sum' was literally the topmost line. It reached English through Old French 'somme.' The same root crowns 'summit,' 'summary,' and 'supreme'—all things at the peak.
