Question

Which of the following correctly uses absolute value to show the distance between -60 and 11?

Answer 1

The absolute difference between any two real \(a\) and \(b\) is given by \(|a-b|\). This is symmetric in the sense that the order of the terms in the argument doesn't matter:
\[|a-b|=|(-1)(b-a)|=|(-1)||b-a|=|b-a|\]
