Notice that when labeling the clock with our numbers it is only \(0,1,2,3\) with modulus \(4\) because we computed \(m-1\) to get a clock of modulus \(4.\) So to compute \(8\) mod \(4\), we start at \(0\) and move over data-equation="4">\(4\) positions data-equation="8">\(8\) positions  clockwise. By doing this, we land on \(0.\)
