That sounds like me.
A woman went to the psychiatrist:
Woman: My Husband thinks he is a refrigerator...
Psychiatrist: Don't worry, it will wear off
Woman: No, you don't understand. He sleeps with his mouth open, and the light keeps me awake!!

I am using circles to mean units, like building blocks. When you use units, they're generally the same size, no?
Once again, sorry for the confusion...

Oh, you mean if a is negative or not, and you will divide by it...
I'm guessing you have to solve a first, if not, ask your teacher!
Or, you could assume a is positive, until it is positively proven that it is negative...
I guess you have to do it by trial or error:/
You're right, this is confusing!
#541 Re: Help Me ! » inequalities » 2007-11-05 22:15:16
Even if it is negative, you will still flip the sign when you divide by a negative number for example:
-5<4
-5(-2)<(-2)4
10<?-8
10>-8
See?
Just a thought though...

Sorry. Same problem as before...
#544 Re: This is Cool » x triangled » 2007-11-04 23:18:02
i'm not sure i understand that explanation. What do you mean, number of circles? how big are the circles? and what do you mean by 'make a square'?
I mean that ,for example, if you want to get 5 squared you: ooooo
ooooo
ooooo
ooooo
ooooo
So, you find out how many units are needed to create a circle with that side.
Same with triangling it: o
oo
ooo
oooo
ooooo
I just meant circles as units. Sorry for creating confusion, Mikau. Peace?
