How many terms are there in (7mn-3m+5)?
Answer and explanation
Correct answer: 3
Terms in an expression are separated by addition or subtraction signs. Here the terms are \(7mn\), \(-3m\), and \(5\), so there are 3 terms. The term \(-3m\) must be counted separately, with its negative sign. Exam tip: Count parts separated by \(+\) or \(-\), not factors joined by multiplication.
