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. Minus 1 plus 1, they just cancel out. Now, when this term right over here is negative, and that's going to happen for x is less than 1, well, then the absolute value is going to be the opposite of it. You give me the absolute value of a negative number, it's going to be the opposite.
