Description

In fact, you don’t necessarily have to look for examples in papers, as the sentence pattern “Let X be Y.” is most commonly found in mathematics textbooks. For instance, if you want to set $n$ as a natural number,

• “Let $n$ be a positive integer number.”

As seen in the introduced example sentences, regardless of what the subject S is, the verb is written in its base form. If there is anything to pay particular attention to in these sentences, it would be matching the number of subjects and predicates. Meanwhile, this sentence can also be written more succinctly and simply as a formula like this:

• “Let $n \in \mathbb{N}$.”
