I Still Don't Know My Operator Precedence
When you're staring at an expression like a + b * c / d - e and your brain just... nopes out. Sure, you COULD memorize the operator precedence table like some kind of mathematical wizard, OR you could just throw parentheses at everything like you're building a fortress of clarity. The calculator might know its order of operations, but do you trust it? ABSOLUTELY NOT. Better slap those parentheses around every single operation just to be safe. Is it elegant? No. Does it work? Also questionable. But at least you know EXACTLY what's happening, even if your code looks like it's wearing braces on its teeth. Pro tip: PEMDAS is great until you realize programming languages have like 47 different operator precedence levels and bitwise operators lurking in the shadows.

Operator Precedence Trust Issues
The paranoia is real. Nothing says "trust issues" like wrapping your calculator in parentheses just to make absolutely sure it calculates 2+3*4 as 2+(3*4) instead of (2+3)*4. That's the difference between getting 14 and 20, and I'm not taking any chances with my code logic. The calculator says it follows PEMDAS, but do I believe it? Absolutely not. Those extra parentheses are basically the programming equivalent of wearing both a belt AND suspenders.

Rust Semicolons Are Different
In Rust, semicolons aren't just punctuation—they're existential decisions. The language is notorious for treating expressions without semicolons as return values, while statements with semicolons return nothing. So that "missing semicolon" isn't missing at all—it's an "excess" one that turned your perfectly functional code into a void of nothingness. Four hours of debugging later, you realize you've been therapy-couch worthy all along.
