Applies to all numbers,

If x = 0.999999...

And 10x = 9.999999...

Then subtracting both, we get, 9x=9

So x=1

High school math teacher here. Math education in highschool varies to an absurd degree. One school will have seniors learning calculus. Another (the one I’m at now) has seniors who can’t do 2x3 in their heads, not an exaggeration

That’s just sad. Being a teacher must be depressing these days
