How will you write the sum of (n) and (12) in algebraic form?
Answer and explanation
Correct answer: \(n+12\)
The word ‘sum’ means that the two quantities must be added. Therefore, the sum of \(n\) and \(12\) is \(n+12\). \(12n\) represents multiplication, while \(12-n\) and \(n-12\) represent subtraction. Exam tip: Match words such as sum, difference, and product with \(+\), \(-\), and \(\times\), respectively.
