H) {46-[26:2+(18-6X2):(4x2-5)]x3}x (15-10)
i) {[4500:(-100)-90:2-(-90)]:1999}x25
J) (-1800+1250):10-220:11-(1200:40-600:15+25

Dau coroana .. pls

Answer 1

h) {46-[26:2+(18-6X2):(4x2-5)]x3}x (15-10)=5
={46-[13+(18-12):(8-5)]x3}x5=
=[46-(13+6:3)x3]x5=
=[46-(13+2)x3]x5=
=(46-15x3)x5=
=(46-45)x5=
=1x5=
=5
i) {[4500:(-100)-90:2-(-90)]:1999}x25=
=[(-45-45+90):1999]x25=
=[(-90+90):1999]x25=
=0
j) (-1800+1250):10-220:11-(1200:40-600:15+25)=
=(-550):10-20-(30-40+25)=
=-55-20-15=
=-90
