Answer 1

(340+13+47):100-3=400:100-3=4-3=1
22[59+2×(5+56)-1]:9=22[59+2×61-1]:9=22[58+122]:9=22×180:9=3960:9=440
8+3×[4+5×(6+56)]-90=8+3×[4+5×62]-90=8+3×[4+310]-90=8+3×314-90=942-82=860
8+1×[8+8×(8+64)]+308=8+1×[8+8×72]+308=316+1×[8+576]=316+1×584=316+584=900
(1478-1125+522):7×4=875:7×4=125×4=500
5+5×[5+5×(5+25-25)]+1=5+5×[5+5×5]+1=5+5×30+1=6+150=156
7+[(7-1)×7-(1-1)]:7+777=7+[6×7-0]:7+777=7+42:7+777=784+6=790
