Answer 1

a) (93+3):4+9×5×0=96:4+9×5×0=24+9×5×0=24+45×0=24+0=24
b)164+69:23-(80-40):40=164+69:23-40:40=164+2,91-40:40=164+2,91-1=166,91-1=165,91
c)770:10:11×(72:6-36:12)=770:10:11×(12-36:12)=770:10:11×(12-3)=770:10:11×9=77:11×9=7×9=63
d) 2×[409-90:(7-2)]-6=2×(409-90:5)-6=2×(409-18)-6=2×391-6=782-6=776
