va roooooog!!!!!! dau coroana!!!!!

Answer 1

a)3x3+[3+3:3x(3+3x3)]:15=
=9+[3+1x(3+9)]:15=
=9+(3+12):15=
=9+15:15=
=9+1=10

b)812-4x[6x(61-3600:12:30)]:9=
=812-4x[6x(61-300:30)]:9=
=812-4x[6x(61-10)]:9=
=812-4x(6x51):9=
=812-4x306:9=
=812-136=676

c)[214+240:(16-2x5)]x25-25:25=
=[214+240:(16-10)]x25-1=
=(214+240:6)x25-1=
=(214+40)x25-1=
=254x25-1=
=6350-1=6349

d)90+7x[161412000:(18-10)]-16=
=90+7x(161412000:8)-16=
=74+7x20176500=
=74+141235500=141235574

e)44+8x[280:(37-1480:20:37)]:32-7=
=44+8x[280:(37-2)]:32-7=
=44+8x(280:35):32-7=
=44+8x8:32-7=
=44+64:32-7=
=44+2-7=39

f)18x8+560:[5x40:(220-2x60)]=
=144+560:[200:(220-120)]=
=144+560:(200:100)=
=144+560:2=
=144+280=424
