Cine le rezolva pe toate primește coroana

Answer 1

a. [(1456+4579)-2859:3]×10=
=(6035-2859:3)×10=
=(6035-953)×10=
=5082×10=
=50820

b. [(975:5)+(421 111- 421 086)]:(27 590 - 27 580)=
=(195+25):10=
=220:10=
=22

c. 70 000-(57 700 :100+32×41:4:8+1382):1000=
=70000-(577+1312:4:8+1382):1000=
=70000-(577+328:8+1382):1000=
=7000-(577+41+1382):1000=
=70000-2000:1000=
=70000-2=
=69998

d. 820 034-[(328 342-263 127)×11]+7059×48=
=820034-(65215×11)+7059×48=
=820034-717365+7059×48=
=820034-717365+338832=
=102669+338832=
=441501

Answer 2

A) [(1 456+4 579)-2 859:3]×10=
=(6 035-953)×10=
=5 082×10=
=50 820


B) [(975:5)+(421 111-421 086)] : (27 590-27 580)=
=(195+25):10=
= 220:10=
=22


C)70 000-(57 700:100+32×41:4:8+1 382):1 000=
=70 000-(577+1 312:4:8+1 382):1 000=
=70 000-(577+328:8+1 382):1 000=
=70 000-(577+41+1 382):1 000=
=70 000-2 000:1 000=
=70 000-2=
=69 999


D)820 034-[(328 342-263 127)×11]+7 059×48=
=820 034-(65 215×11)+ 7 059×48=
=820 034-717 365+338 832=
=102 669+338 832=
=441 501
