It's a bit hard to understand your question; I assume you mean a quarter of the difference between a number and 7. Let's call that number x, then the algebraic expression is 1/4 |x - 7| Where the | symbols represent the absolute value or modulus of the expression between them, which always gives you a positive number. Imagine the 1/4 is written with the 1 over 4 like it would usually be. For x = 3, you get 1. Otherwise if you want to allow negatives, you can say 1/4 (x - 7) which for x = 3 gives you -1.
