WebMore Formal. More formally we have: Which says the absolute value of x equals: x when x is greater than zero; 0 when x equals 0; −x when x is less than zero (this "flips" the number back to positive); So when a number is positive or zero we leave it alone, when it is negative we change it to positive using −x.
