I migrated when DIGG died, so this all feels pretty familiar to me.

My manager talked me into buying Diablo IV since I was into DnD.
I don't know why people play games that require grinding when there are so many better options.

Its not that there's no definition for the notation, but if you fall back to commonly held definitions, there is divergence in common definitions without the parenthesis. Plenty of calculators, especially old ones, don't respect PEMDAS, so the so by adding brackets your expression is going to fit the intended operations in more commonly used systems than had you left the brackets out.
I also do think its a bit more readable as your eyes are initially drawn to the first operation, you can start evaluating expressions without even parsing the rest of the equation, or you can just block out that entire chunk when you start looking at how many terms are in the equation. That's subjective though, so to each their own.
I'm an engineering major, we learn all of the edge cases as "well technically this isn't always true, but we'll just pretend it is because the results are close enough"
Every value of Y works for X=0, the equation simplifies to Y=Y, so X=0 is just like Y=9.
In the limit as X->infinity, you get Y = 9 again.
X(1+Y) + Y = 10*X + Y lim X->inf Assuming Y is finite, you drop the non-X terms
X(1+Y) = 10*X lim x->inf
Here, because X is non-zero and equal to itself, you can cancel them (I assume, IANA Mathematician) 1 + Y = 10 Y = 9
ps, top, and kill along with GIMP aren't good enough?
I do like the pretty charts though so I can see how close my GPU is to melting.
Didn't we just have 7 of the hottest days on record in a row? Nature's fucked, but the shitposting boards are back baby!

Notation without a definition of what notation you're using is always going to be ambiguous.
If I wrote
6 9 * 6 9 + +
You wouldn't know what that is, until I told you it was reverse polish notation, then you would know it resolves to 69 and does the same operations as the original equation.
Huh, that's true of any number that ends in 9.
XY + X + Y = 10*X + Y
Y's cancel,
XY = 9X => Y = 9 for any non-zero finite value of X.
so for 69? X = 6, Y=9
(6*9) + 6 + 9 = 10*6 + 9
54 + 15 = 69
69 = 69 (nice!)
429? X = 42 Y = 9
(42*9) + 42 + 9 =10*42 + 9
(378) + 51 = 429
429 = 429
Even if 10X+Y doesn't equal something that ends in 9 it works
X=3.14 Y=9
(3.14*9) + 3.14 + 9 = 10*3.14 + 9
28.26 + 12.14 = 40.4
40.4 = 40.4
Doesn't work if Y =\= 9:
68? X = 6 Y = 8
(6*8) + 6 + 8 ?= 10*6 + 8
(48) + 14 ?= 68
62 =\= 68
