a)[3420:36-(5760:48-2880:36)]:5
b)94+[(106*5003-4009*102):607-2]:33
c) [2560-48*(2304:48_2208:92)]:64+8
d)123-5*{42:6+[7*(300:5-36: 2)-60]:18}

Answer 1

a)[95-(120-80)]:5⇒[95-(40)]:5⇒55:5=11
b)94+[(530318-408918):607-2]:33⇒94+[121400:607-2]:33⇒94+[200-2]:33⇒94+198:33⇒94+6=100
c)[2560-48*(48-24)]:64+8⇒[2560-48*24]:64+8⇒[2560-1152]:64+8⇒1408:64+8⇒22+8=30
d)123-5*{7+[7*(60-18)-60]:18}⇒123-5*{7+[7*42-60]:18}⇒123-5*{7+[294-60]:18}⇒123-5*{7+234:18}⇒123-5*{7+13}⇒123-5*20⇒123-100=23
