Problem: evaluate : | 6 - 8 ( 3 - 12 ) | - | 5 - 11 | = ?
Rationale: "according to order of operations , inner brackets first . hence | 6 - 8 ( 3 - 12 ) | - | 5 - 11 | = | 6 - 8 * ( - 9 ) | - | 5 - 11 | according to order of operations , multiplication within absolute value signs ( which may be considered as brackets when it comes to order of operations ) next . hence = | 6 + 72 | - | 5 - 11 | = | 78 | - | - 6 | = 78 - 6 = 72 correct answer c ) 72"
annotated_formula: subtract(subtract(6, multiply(8, subtract(3, 12))), negate(subtract(5, 11)))
