Expert writing Tips
Best practice
When using "numerical couple", ensure the context clearly establishes the relationship or dependency between the two numbers. This helps avoid ambiguity and strengthens the intended meaning.
Common error
Avoid implying a direct cause-and-effect relationship solely based on the presence of a "numerical couple". The term simply denotes a pair of related numbers; further analysis is needed to determine any underlying causality.
