Answer 1

a)
8+3*(154-129)+16*(185-148)+186=
8+3*25+16*37+186=
8+75+592+186=
83+778=861

b)
824-2*(8+3*16)-35/(14-3*3)-75/(5+0)=
824-2*(8+48)-35/5-75/5=
824-2*56-7-15=
824-112-7-15=
712-7-15=690

c)
(612/3-525/5)/9+14*(144/8+225/3)/7
(204-105)/9+14*(14+75)/7=
99/9+14*99/7=
11+1386/7=
11+198=209

d)
4008-6*(951*19-945*18)/3+12*(3592/8+1932/6)/4=
4008-6*(18069-17010)/3+12*(449+6)/4=
4008-6*1059/3+12*455/4=
4008-6354/3+5460/4=
4008-2118+1365=
1890+1365=3255

e)5+5x(5+5x5):5+5x(5+5)x(5+5:5)=
5+5*30/5+5*10*6=
5+150/5+50*6=
5+30+300=
335

f)
15+15x(15+15x15)-15x(15x15-15)=
15+15*290-15*260=
15+4350-3900=
4365-3900=465

g)
13050-3x(187+23x108)+(825x93-48400):5=
13050-3*(187+2484)+(76725-48400)/5=
13050-3*2671+28325/5=
13050-8013+5665=
5037+5665=10702
