9^1/2
Too many idiots get this wrong and WILL result in a logic error whilst programming.
Someone tried to argue my answer down, but if you put it through your program, you'll get the right answer.

or 4.
9^1 ... /2 = 4 9^(1/2) = 9 (and 9^0.5 gives me an error...waa!)

...how do you get 4? Maybe your calculator is doing some sort of rounding or is returning an integer result.
4' not the answer and neither is 9. |

it doesn't make sense D: 9^0.5 so i could do 9*4.5, soooo... 40.5 or 3 like the calculator says? |

oh wait Lua gave me different answers:
9^0.5 -- 3
9^1/2 -- 4.5
9^(1/2) -- 3 |

@Corecii
Thank you.
I was just afraid for the kids here after three people argued me against that answer (it was a much larger equation, but the confusion was this).
The answer is 4.5.
9^1/2= 9/2= 4.5
The answer is NOT 3. Just makin' sure you guys understood this.
Sorry for wasting forum space. |

Was using Go before.
Lua's answers seem more logical. |

It's quite simple really, you don't need a calculator or anything.
9^1 = 9 9/2 = 4.5 |

The reason people are debating should be obvious to you.
When it's written down on a page, it may appear as:
0 1/2 !
(The exclamation mark and 0 are meant to look like a 9, but forum will most likely mess it up.)
That would be 3.
By order of operations though, since it's written down on a pretty much single-height line, it'd turn out to be 4.5. |

@trapping
I know, but this is ASCII line math. It's not a scientific equation.
There are different rules. |

| I was stating the reason why people are debating against you. And it's a very good reason. In situations like this you should explicitly put the 9^1 in parentheses to make it clearer. |

trapping, you don't have to make it clear. ASCII line math has different rules than the setup of an algebraic equation.
This is what people need to get.
When you write an equation:
#^#/(#*#+#)^#
Expect me to solve it as ASCII line math. Because that's what it is.

| I'm sure he knows t's different, as do I. But to the people who you were arguing with know? They may of seen it differently. Even if that is the case, it's no different. In both cases they were looking at it the wrong way and JohnFrimp (Who's you realy accountzzzz?!!?!) is right. In both cases the arguers say it as 9^(1/2), which is wrong. The reason may be different, (they MAY OF seen it as ascii art in their heads, but probably not) but the result is still the same. |

| 1/2 could've been read as a fraction, which caused the confusion. |

| If this were C, the answer would be 1/2. |

| 9^1/2 is not 9^(1/2), so 4.5 |

Lua doesn't use pemdas. It just goes in order of the equation. So you should use:
9^(1/2) |

wat. I don't know of a language that doesn't use order of operations. |
