Line 1: 99=9999=9999=99
Line 2: 180−81=220−121180-81=220-121180−81=220−121
Line 3: 81−180=121−22081-180=121-22081−180=121−220
Line 4: 92−2⋅9⋅10+102=112−2⋅11⋅10+1029^2-2\cdot9\cdot10+10^2=11^2-2\cdot11\cdot10+10^292−2⋅9⋅10+102=112−2⋅11⋅10+102
Line 5: (9−10)2=(11−10)2(9-10)^2=(11-10)^2(9−10)2=(11−10)2
Line 6: 9−10=11−109-10=11-109−10=11−10
Cancelling −10-10−10 from both sides, we obtain 9=119=119=11
In which line I did the mistake?
