19×96-962÷74 (320+180)÷50×4的简便运算过程
是两个题

19×96-962÷74 (320+180)÷50×4的简便运算过程是两个题
19×96-962÷74
=20*96-96-13
=1920-109
=1811
(320+180)÷50×4
=500/50*4
=10*4
=40

19×96-962÷74 (320+180)÷50×4
= 19*96 - 962*74*500*50*4
= 19*96 - 962*74*10*4
= 19*96 - 13*40
= (20-1)*96 - 520
= 1920 - 96 - 520
= 1824 - 520
=1324

19×96-962÷74(320+180)÷50×4
=1824-13×500÷50×4
=1824-520
=1304

19×96-962÷74
=(20-1)(100-4)-74×13÷74
=2000-100-80+4-13
=1811
(320+180)÷50×4
=500÷50×4
=10×4
=40

19×96-962÷74
