Beauty of Math


Beauty of Math

Just realised that we can add to those equations the following ones on top of the pyramid and thus biuld an hour glass:

-123456789*9-10 = -1111111111

-12345678*9-9 = -111111111

-1234567*9-8 = -11111111

-123456*9-7 = -1111111

-12345*9-6 = -111111

-1234*9-5 = -11111

-123*9-4 = -1111

-12*9-3 = -111

-1*9-2 = -11

0*9+1 = 1

1*9+2 = 11

12*9+3 = 111

123*9+4 = 1111

1234*9+5 = 11111

12345*9+6 = 111111

123456*9+7 = 1111111

1234567*9+8 = 11111111

12345678*9+9 = 111111111

123456789*9+10 = 1111111111
