How do you solve this math problem?...
We encountered what we thought is a rather simple math problem...
10 + 10 x 0 =
And yet we've debated for hours how to solve this and I'm under the impression that 20 is the correct answer but the calculator says 0... something must be wrong with the calculator or something...

10 + 10 x 0 =

The correct answer is 10.
Multiplication takes priority, therefore the right part of the sum becomes 0.

Re: How do you solve this math problem?...
If you're using a graphing calculator, then yes, it's very wrong. If you're using one of those standard arithmetic calculators, then it's just doing what you're telling it to do. It's wrong, but it's not the calculator's fault.
Also, I'm fairly certain the answer is 10. Google agrees with me.

Yeap! The next time you write in a calculator, you should type 10 + (10 x 0), or begin with the multiplication, so it can calculate properly.

10, like everyone said. Make sure, to use parenthesis in calculators.

If you have a Reverse Polish Notation calculator, you should type:Arcanum wrote:Yeap! The next time you write in a calculator, you should type 10 + (10 x 0), or begin with the multiplication, so it can calculate properly.
10 enter 10 enter 0 x +
Of course, if you have a RPN calculator, you probably don't need to ask.

Re: How do you solve this math problem?...
There are two kind of calculator. It's my own name (I don't know the official name) which is scientific (or mathematic) calculator and the other is kiosk calculator (cheap calculator that small vendor usually use). In my language, I personally call the later as "Kalkulator Tukang Sayur" since they are extremely cheap (less than US$1).
According to math, the answer should be 10, because X have higher priority than +. So if you didn't add any brackets, the calculator would automatically count like this:
But if you use the second type of calculator, since they have minimal capability of calculation, parenthesis, and memorizing result, it will count it like this:
How could you know if a calculator fall under which category? Insert this formula on the calculator.
If it's a scientific calculator, the result should be back to 10
If it's the latter, then the result would be 9.99999...
According to math, the answer should be 10, because X have higher priority than +. So if you didn't add any brackets, the calculator would automatically count like this:
Code: Select all
10 + (10 x 0) = 10 + 0 = 10
Code: Select all
10 + 10 = 20, then 20 x 0 = 0
Code: Select all
First insert: 10 / 3, and then after showing the result (should be 3.333333...) multiply it by 3 (x 3).
If it's the latter, then the result would be 9.99999...

Re: How do you solve this math problem?...
I can't help but think this is a troll. Unless Mugenjohncel was making incredibly detailed artwork and coding up games in elementary school, I find it hard to believe that he is now asking such a question.
The fact that so many people answered seriously is baffling.

Re: How do you solve this math problem?...
Hmmm... I think it's because Mugenjohncel is a long time LSF users and there's no point for him to start trolling. So everyone just want to help, for whatever reason he needs... Perhaps we should PM him? Who knows if someone stole his password and start posting random message?

And to clear things up
Lol!... No... Unbelievable it may seem... this forum is one of those few places where I don't troll that much... 4chan, 7chan, Gurochan even Bunbunmaru but not Lemmasoft Forums... This place is practically my hometown... (Ok sometimes but not often )pondrthis wrote:I can't help but think this is a troll.

The reason why I asked this question is we really did have a debate (me and my buddies under the influence of alcohol) regarding this... being a bunch of layman's we will obviously take everything literally and calculate the thing in order which is 10 + 10 = 20 then comes the x 0 which we believe is nothing so result will stay 20 but we were surprised when we used our phones (and the Beerhouse's calculator) and got 0 which is really something we didn't expect to see... so we naturally assumed either this is a long undiscovered bug in the calculators or were doing something wrong which we didn't know...
Lol! This I don't deny but I generally do this outside of Lemmasoft... the closest to trolling I could do here is this...pondrthis wrote:(Alternatively: the guy is known to get kicks out of random shit.)

And yet, even this one really is an existing project with much progress done already...
Now here's few of those occasions where I really troll...

Yeah, mugen's like a troll who doesn't really troll (here anyway). It's an enigma. Kind of like a chocolate bunny that tastes like broccoli.

Meaning: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction in that order (but multiplication on same level as division, and addition on same level as subtraction.)
