Question

Which shows the product of a number n and 12?
A: n-12
B: n/12
C: 12n
D: n+12

Answer 1

The correct answer is C. Often, the multiplication sign is dropped when obvious, and so
`12n` means "twelve times n".

For the record:

`n -12` is the difference between a number n and 12

`\cfrac{n}{12}` is the ratio between a number n and 12

`12n` is the multiplication between a number n and 12, it's the same as
`12 * n`

`12+n` is the sum between a number n and 12
