If the number is x, then abs(8-x) or |8-x|
difference of eight and a number
"the difference between a number and eight is twenty-two
One number is eight more than twice another if their difference is 25. The larger number is 42
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.
The difference is that number.
difference of eight and a number
twice the difference of three times a number and eight
"the difference between a number and eight is twenty-two

x - (8 - x)
one third of the difference between ten and a number
