Using mathematical notation this would be written: (1/2 + -3/4) x |-5/6 - 13/8| = -1/4 x 59/24 = -59/96
“Difference” is defined as the positive distance between the values on a number line, hence the absolute value brackets. Eg the difference between 2 and 9 is 7 The difference between -2 and -8 is 6 The difference between-5 and 4 is 9
