8+n
n/6 + 3
-8 + 13/N, where N ≠0.
n/8 + 3
If you call the number "n", then the expression would be "n+5".
31 plus n
n+19
N/8
n - 8 is the expression for the difference of eight and a number.'Number' is a variable, so the variable must be a letter (in this case, 'n'). 'The difference' is going to be the subtraction symbol that is in between the 'number' and eight, so it must be n - 8. It could, of course, be 8 - n.
n/6 + 3
-8 + 13/N, where N ≠0.
n+7 or X+7
n/8 + 3
n+81
Un = n + 32
If you call the number "n", then the expression would be "n+5".
It is 8*(-4)N which is -32N
