Yeah the thing is that I'm not learning exactly why I'm doing these things. We're not learning theory, just applications. I'm just given the steps and that's the end of that lol. Luckily my assignment is finished (TI-89 ftw), and I'll just have to ask in class how exactly to do a 3x3 before the...

How did they get the answer? I went over how to do 2x2 w/ someone but 3x3 seems different.
Basically this is how I'm...
The woman probably got forced down to $3 to begin with. Pawn guys set their mind to a price and it's hard to make them budge because they think in terms of how much they can resell it for after they acquire the item.
So when the man picks up the necklace, he's most likely going to be paying...
Lol how did you get an "E"? Sorry, I burst out laughing when I saw that. Anyways...
It seems too personal and informal. I think you need to tone down on all the explicit details and take the time to "craft" your thoughts properly. Stuff like this:
"My heart rate was too fast and I was too...
Basically, I'm going to be enrolling into a local university soon but there is a small dilemma as to what exactly I should major in. At first, I thought I wanted computer science but after doing a basic 3d game and tons of other little small projects in various languages (word processor, social...
My friend, I have no clue why I'm getting the wrong answers. O_o
I was under the impression that you just plug the numbers in and it outputs correct answers.
Ok yeah but there's another method that looks like this right:
\frac{a}{b}-\frac{e}{f}=\frac{a*f-b*e}{f*b}
So I'm trying to find out when that's applicable and when it's not.
I don't think you guys understand what I'm saying. I'm saying that when I use the LCM method it's different from when I use the cross multiplication method. O_o
But shouldn't it yield the same result? I'm obviously missing the logic of the cross multiplication method.
...which is this...
Homework Statement
Simplify:
3c-(\frac{2a+c}{8}-\frac{a+2c}{4})
The Attempt at a Solution
I got this:
\frac{9c}{8}
But the answer is:
\frac{27c}{8}
It's simply an issue with whether I find the LCM or I use this formula:
\frac{a}{b}-\frac{e}{f}=\frac{a*f-b*e}{f*b}
If...
