Question

Write an expression for the sequence of operations described below:

add 6 and n, then subtract 3 from the result.
What is the expression for this sequence?
A) n+3
B) n+9
C) n−3
D) n−9

Answer 1

The expression for adding 6 to n, then subtracting 3, simplifies to n + 3. This matches answer option A) n+3.

To find the expression for the sequence of operations described, you should follow the order of operations, which is to add first and then subtract. When you add 6 to n and then subtract 3 from the result, you can write this sequence as (n + 6) - 3. However, since there are no parentheses dictating a different order, this simplifies directly to n + 6 - 3.

If you combine the constant terms, 6 and -3, you get +3. Therefore, the simplified expression would just be n + 3, which matches answer option A).

The answer is as follows:

• The expression for the sequence is: n + 3.
• The correct answer is A) n+3.
