Question

va rog
a ) 32×51:8×200-[775:25×(172-85)]
b) [700-(505-135×2-38×3)×2]-100
c) 1000-[(250:25+330:3)-(30×2-5×8)]×4
pentru cel mai bun dau coroana
​

Answer 1

a)32×51:8×200-[775:25×(172-85)]
=1632:8×200-(31×67)
=204×200-2077
=40800-2077
=38723

b)[700-(505-135×2-38×3)×2]-100=
=[700-(505-270-114)×2]-100
=[700-(235-144)×2]-100
=(700-91×2)-100
=(700-182)-100
=518-100
=418

c)1000-[(250:25+330:3)-(30×2-5×8)]×4=
=1000-[(10+110)-(60-40)]×4
=1000-(120-20)×4
=1000-100×4
=1000-400
=600
