And when the absolute value is non-negative, if you're taking the absolute value of a non-negative number, then it's just going to be itself. The absolute value of 0 is 0. Absolute value of 1 is 1. Absolute value of 100 is 100. So then, you can ignore the absolute value for x as greater than or equal to 0. for x is greater than or equal to 1. x is greater than or equal to 1, this thing right over here is non-negative. And so it'll just evaluate to x minus 1. So this is going to be x minus 1 plus 1, which is the same thing as just x.
