Answer 1

a) 3+3x(3+1x12):15=3+3x15:15=6
b) 812-4x(6x51):9=812-4x306:9=812-136=676
c) (214+240:6)x25-1 =(214+40)x25-1=254x25-1=6349

Answer 2

a)

3+3×[3+3:3×(3+3×3)]:15=

3+3×[3+1×(3+9)]:15=

3+3×(3+1×12):15=

3+3×(3+12):15=

3+3×15:15=

3+45:15=

3+3=

6

b) 812-4×[6×(61-3600:12:30)]:9=

812-4×[6×(61-300:30)]:9=

812-4×[6×(61-10)]:9=

812-4×(6×51):9=

812-4×306:9=

812-1224:9=

812-136=

676

c) [214+240:(16-2×5)]×25-25:25=

[214+240:(16-10)]×25-1=

(214+240:6)×25-1=

(214+40)×25-1=

254×25-1=

6350-1=6349
