Find a way to make twenty-four given three five numerals, one one number, and the four arithmetic operations, plus, minus, times and divide. You can use as many operations symbols as you need (repetitions are ok), and have to use only the four numerals. It is possible to use parentheses. It isn't possible to combine the four numbers any other way (these two things are expressly forbidden: exponentiation - raising to a power; concatenation - adjoining number symbols).

Concisely,

Given: 5, 5, 5, 1, +, -, *, /

Find: 24

Note: Parentheses permit stating how you group operations.
