Expert writing Tips

Best practice

When using "the sum of", ensure that the elements being added are clearly defined and relevant to the context. For example, "The sum of the project costs exceeded the initial budget."

Common error

Avoid using "the sum of" when referring to non-additive or abstract concepts. It is more appropriate to use "the essence of" or "the core of" when describing such ideas. For example, instead of saying "The sum of the problem is miscommunication", say "The core of the problem is miscommunication".
