а)410*(95+28.860:39):167*40-4564014:(441090:870)=?

б)(791315:983*2030-1578595)*(932*59:54988-0:75914)=?

Answer 1

1)410*(95+740)/6680-4564014/507=410*835/6680-9002=51,25-9002=72998

28860/39=740

95+740=835

410*835=342350

342350/167=2050

2050*40=82000

441090/870=507

4564014/507=9002

82000-9002=72998

 

2)(791315:983*2030-1578595)*(932*59:54988-0:75914)=55555

791315:983=805

805*2030=1634150

1634150-1578595=55555

932*59=54988

54988/54988=1

0/75914=0

1-0=1

555555*1=55555
