evaluate : | 9 - 8 ( 3 - 12 ) | - | 5 - 11 | = ?
according to order of operations , inner brackets first . hence | 9 - 8 ( 3 - 12 ) | - | 5 - 11 | = | 9 - 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 = | 9 + 72 | - | 5 - 11 | = | 81 | - | - 6 | = 81 - 6 = 75 correct answer a ) 75
subtract(subtract(9, multiply(8, subtract(3, 12))), negate(subtract(5, 11)))
