Answer 1

a) 1309+6792-54:9:3*8=8085
1309+6792-6:3x8=8085
1309+6792-2x8=8085
8101-16=8085

b) 10001-9036-64:8*9+4:2*8-109+7*7=849
965-8x9+2x8-109+49=849
965-72+16-109+49=849
893+16-109+49=849
909-109+49=849
800+49=849

Answer 2

a) 1309+6792-54:9:3×8=
=8101-6:3×8
=8101-2×8

b) 10001-9036-64:8×9+4:2×8-109+7×7=
=965-8×9+2×8-109+49
=965-72+16-109+49
=893+16-109+49
=909-109+49
=800+49
