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.
The corresponding equation, is solve n when :- 2(n - 4) = -8 2n - 8 = -8 2n = -8 + 8 = 0 n = 0
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
7 - n
If the number is n then it is |8 - n| or abs(8 - n)
n-8

8-n

Well, darling, 5 times the difference of a number and 8 is simply 5(n-8), where n is the mysterious number you're working with. So, if you want to find out the result, just plug in your number and do the math. Easy peasy, lemon squeezy!
N - 8 = 22 (:
Abs(n - 8) = 22
Whats n+8
s= -8 + n, or s=n - 8, where s is the sum and n is the number
What is the difference between 8 and some number, n (question mark). What is some number, n, less than 8 (question mark). Wiki won't let me use a ? at the end of a sentence because their computer dose not recognize that as an answer.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
