evaluate : | 7 - 8 ( 3 - 12 ) | - | 5 - 11 | = ?
"according to order of operations , inner brackets first . hence | 7 - 8 ( 3 - 12 ) | - | 5 - 11 | = | 7 - 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 = | 7 + 72 | - | 5 - 11 | = | 79 | - | - 6 | = 79 - 6 = 73 correct answer c ) 73"
subtract(subtract(7, multiply(8, subtract(3, 12))), negate(subtract(5, 11)))
