Answer 3

Don't just give them the answers. We want to try to get them to tell us the answers themselves, making sure that they understand how to get that answer.

Answer 4

A "difference" is a subtraction between two numbers. Since we do not know what number "n" is, we would say "n" as "a number n" because it is undefined.

Answer 5

Answer 6

One way to solve these types of problems is to completely write out in words what the problem is doing.

3(n-1)= three times n (a number) minus 1

In the answer choices, minus is referred to as "difference"

three times the difference of n (a number) and 1

We know that "n-1" is in parentheses so this operation must come first. This is why "times the difference" is used, it shows that some operation is occurring before we multiply by 3.

Therefore, than answer would be D.
