The correct interpretations of the expression \( n + 5 \) are:
- the sum of a number and 5
- the total of a number and 5
- 5 more than a number
The incorrect interpretations are:
- the difference of a number and 5 (this would be expressed as \( n - 5 \))
- 5 is greater than a number (this does not represent the expression \( n + 5 \))
- 5 less than a number (this would be expressed as \( 5 - n \) or \( n - 5 \))
So, the three correct interpretations are the first three options listed above.
