Answer 1

824-2x(8+48)-35:(14-9)-5:5
=824-2x56-35:5-1
=824-112-7-1
= 712-7-1
=705-1
=704
___________

(1836-125)+9+14x(1152-225+3)+7
= 1711+9+14x930+7
= 1720+13020+7
= 14747.
____________

Answer 2

 824-2*(8+3*16)-35:(14-3*3)-5:(5+0)=
=824-2x(8+48)-35:(14-9)-5:5=
=824-2x56-35:5-1=
=824-112-7-1=
=712-7-1=
=705-1=
=704

b)
(612*3-525:5)+9+14*(144*8-225+3)+7=
=(1836-105)+9+14x(1152-225+3)+7=
=1731+9+14x930+7=
=1740+13020+7=
=14 767


e)
5+5*(5+5*5):5+5*(5+5)*(5+5:5)=
=5+5x(5+25):5+5x10x6=
=5+5x30:5+300=
=5+150+300=
=455

f)
15+15*(15+15*15)-15*(15*15-15)-15:15=
=15+15x(15+225)-15x(225-15)-1=
=15+15x240-15x210-1=
=15+3600-3150-1=
=3615-3150-1=
=464

g)
13050-3*(187+3*108)+(82*93-484)=
=13050-3x(187+324)+(7626-484)=
=13050-3x511+7142=
=13050-1533+7142=
=11517+7142=
=18659
