How would you write the product of 3 and a number?
1 Answer
- “The product of a number and three” should be 3n where n is the number.
- IN the answer of the question you would have to explain something like this: Let n be the number. The product then is 3n .
- The reason for this is that you could also let m stand for the number, in which case the answer would be 3m .
