kc: I think she's about to post some work for me to look at. :)
o i gotcha
what would x-0.013=-636 be? would you just add 0.013 to both sides?
That is correct.
I'd be more than happy to verify your actual answer if you want to post it. :)
Sorry, that's incorrect. How exactly did you get that?
6.36+0.013 than put in the negative
Oh, in your original problem you didn't have a decimal after the 6. See a few posts up.
That said, it's still not exactly right by my calculation.
You can't put in the negative after the fact. I get: -6.36 + 0.013 = -6.347
Do you understand why?
Ok, so first thing is first. When negative numbers are involved, order matters.
So, you can't just add 0.013 to positive 6.36. It won't get you the same answer. However, if you wanted to look at it as normal subtraction, you could do it this way: -6.36 + 0.013 = - (6.36 - 0.013)
By pulling the negative out of the equation you reverse all the signs. That makes 6.36 positive, and 0.013 negative. And then it becomes a subtraction problem.
The reason this works is because of how the numbers are organized. I'm sure you've need the number line before. Looks something like: ... -2 ... -1 ... 0 ... 1 ... 2 ... And then on and on in both directions. When we're adding a positive number to a negative number, we're moving closer to 0. So the actual "number part" should get smaller. If it doesn't something has gone wrong.
i don't get it so what would be the answer?
x = -6.347 is the answer. You were right about what you should do to find X, you just did your addition incorrectly.
can you draw the addition?
Sure I can do that. But after that I'll need to leave.
This is how you set it up: |dw:1327285297432:dw|
Then you'll need to change it to subtraction to have this format mate sense, I think.
So, to do that you'll end up with: |dw:1327285440614:dw|
Then, you'll just need to do the subtraction.
Does that help?
Excellent. Feel free to continue posting questions, and keep at it. If imranmeah91 or myininaya or most of the other high level users know you really want to learn, they will help. If they don't see your questions after a few minutes, go into the chat rooms (the green tabs at the bottom) and feel free to try and get their attention there. :)
TY! and to clarify on the previous issue i was just wanting to help people not spam the site
I understand. :) But for future reference, if you need attention try to talk to people in the chat. And sometimes people just aren't online when you need them. Come back later and try to find them in the chat then! Also, with regard to suspensions - for future reference if you get suspended again just wait it out. If you keep coming back with multiple accounts we have to block you from the site and prevent you from signing up. (Which I hate having to do.) Best of luck!
