Salut

Explicație pas cu pas:

100+[(26+308×24÷2-562]÷2=

=100+(26+7392÷2-562)÷2

=100+(26+3696-562)÷2

=100+(3696-536)÷2

=100+3160÷2

=100+1580

=1680

(55-25)×[(282÷3-2)÷2]=

=30x(92÷2)

=30x46

=1380

25+[7×2×18÷2-5×(5×4-36÷3)]=

=25+[14x9-5x(20-12)]

=25+(126-5x8)

=25+166

=191

250×4-[80+(76×13-801÷9)-479]=

=1000-[80+(988-89) -479]

=1000-(80+899-479)

=1000-500

=500

21×[(36×48-40)÷8+(72×41-+12)÷5]+100=

=21x[(1728-40)÷8+(2952-12)÷5]+100

=21x(1688÷8+2940÷5)+100

=21x(211+588)+100

=21x799+100

=16779+100

=16879

540+[(780÷4+380×2)÷5+343]÷6-600=

=540+[(195+760)÷5+343]÷6-600

=540+(955÷5+343)÷6-600

=540+(191+343)÷6-600

=540+534÷6-600

=540+89-600

=629-600

=29

[(480 600÷ 54-500)×8+909]×(100-10×10)=

=[(8900-500)x8+909]x(100-100)=

=(8400x8+909)x0

=(67200+909)x0

=68109x0

=0
