Can someone explain?

Why is \( 123, 456, 789 \times 9 = 1, 111, 111, 111 \)?

Is there any special reason?

@Ajala Singh

Note that the equation you typed is wrong. Instead, what we have is

\[ 123, 345, 79 \times 9 = 111, 111, 111. \] Calvin Lin Staff · 2 years, 7 months ago

@Venture Hi (After accounting for possible arithmetic errors) There is a pattern involved here, so there might be a "special reason".

I elaborated further in this note. Calvin Lin Staff · 2 years, 7 months ago
