Expert writing Tips

Best practice

Use "which sums to" when you want to clearly indicate that you are presenting a total or result of adding several values together, especially in technical or formal writing.

Common error

Avoid using "which sums to" when you actually mean "which sums up", as "sums up" implies a summary or encapsulation of information rather than a numerical total. "Which sums to" is for numerical totals only.
