Answer 2

a)7000-(1780:10+1700)x3+(40:5 x 9)=
7000-(178+1700)x 3+72=
7000-1878 x 3+72=
7000-5634+72=1366+72=1438
b)156 x 8:4+(25x7+36x9:6)-(5000:100:5x68+2):2=
1248:4+(175+324:6)-(50:5 x 68+2):2=
312+(175+54)-(10 x 68+2):2=
312+229-682:2=
541-341=200
c)12+12 x (12+12 x 12-12:12)+12 x 10-12 x 5:4 x 3=
12+12 x (12+144-1)+120-60:12=
12+12 x 155+120-5=
12+1860+115=1987
