lol are legitimately saying this was not a joke?
Parenthesis consists of only two symbols that only require two keyboard keys and a single stroke of a pen to write compared to the four keys and varying strokes of the standard operators
The humble ( ), however, is very easy to see, and it creates neat little windows that don’t leave much room for misinterpretation.
2*7²+5*3³ = accessibility nightmare
(2(7²))+(5(3³)) = readable with clearly defined order of operations
I mean, I guess I have no reason to doubt your word so I’ll just believe you were being serious and respond in kind.
Time savings you might gain from parentheses being easier to write and requiring less keystrokes is lost on you needing to use twice as many since they come in pairs.
Furthermore, with the exception of *, which we don’t even write most of the time, you still need to use all of the other operators even with parentheses, so using them everywhere isn’t even a trade off, it’s a net loss. This also means that parentheses will not help you differentiate between the operators because you’ll still be using them.
Finally, the only reason you find the example I gave easier to read with parentheses is because I used a lot of multiplication, but you have multiplication to thank for that, not parentheses. In most cases, it would have fairly simple expressions like this:
1+2+3+4+5+6+7+8
turned into this:
1+(2+(3+(4+(5+(6+(7+(8))))))
If you truly want to eliminate ambiguity, have a look at reverse polish notation. I find it confusing as hell but some people like it.
Holy fuck. I called you one out of all of those and it was the one who isn’t even a pejorative. I thought you were joking, because your comment sounded like you were joking. There’s really no deeper meaning to that.
That’s what I’m saying, using parentheses won’t make the operators and symbols go away. You’ll still have to stop and hunt for them, you’re just adding parentheses in addition to that.
That’s only true for simple expressions, though. Once you try to type something more complicated, parentheses get very confusing very fast. Anyone who’s ever had WolframAlpha refuse to evaluate an expression because of a missing parentheses knows what I mean.
As for your examples,
In these, the version with parentheses is different from the one without because you want the operations to be done in a certain order that isn’t indicated anywhere.
And in this one, you’re mixing several operators with equal priority on the same line while not indicating which one you want to be done first.
What I’m getting at is that you’ve provided the exact examples where you have to use parentheses so it makes no sense to ask which one is clearer because only one version is correctly written. It would be like me asking you if (24)+1 is clearer than 2*4+1 and concluding parentheses are confusing because you didn’t divine I wasn’t typing twenty four but instead wanted you to multiply the 2 and 4.
Finally, the order of operations isn’t just some arbitrary convention, it might seem that way when we limit ourselves to only numbers but its intuitiveness really shows in algebra. Take the polynomial:
2x²+1
Even if you’ve never heard of the order of operations, there’s absolutely zero confusion about which order you’re meant to do the operations. It would take a madman to decide that “+1” is part of the exponent or that you’re supposed to add the 1 to the x² and then multiply it by 2.
In this case, adding parentheses here would turn it into
2(x(²))+1
which is unnecessary and it gets annoying very fast. For example:
(2(x))+(3(x(²)))+(5(x(³)))+(8(x(⁴)))
vs
2x+3x²+5x³+8x⁴
You might say that’s not fair because this expression clearly needs no parentheses so I just added them to make it seem more confusing and you’d be right but that’s the point: there has to be an arbitrary line where we decide parentheses are no longer necessary and that’s the order of operations. We settled on that because that’s what works in algebra. When it comes to what’s intuitive in arithmetic, left to right is obviously the best (for westerners). Unfortunately for arithmetic, we’ve decided that intuitiveness in algebra is more important than intuitiveness in arithmetic.
