(1/6 x 36 - 7)/(4 + 1/5 x 25)

= (multiply 1/6 by 36 and simplify [36 divided by 6 is 6] and subtract 7 = -1)/(multiply 1/5 by 25 and simplify [25 divided by 5 is 5] and add 4 = 9)

 

answer = -1/9

 

(-5^2 - 10 x (-5) + 5)/(-5^2 + 2 x (-5) - 1)

= (-5 squared is 10. 10 times -5 is -50. 10-(-50) is 60. 60 + 5 = 65)/(-5 squared is 10. 2 times -5 is -10. 10 +(-10) is 0. 0 - 1 = -1)

 

answer = 65/-1 = -65

im in high school (9 grade) and my math is

 

5531/7

and

6748x8

or

3254744545

find the place value of the underlined digit

 

you know the hard stuff

I took Geometry for math when I was in 9th grade. Depending on what you think you might want to do with yourself later on, I would make sure you get Algebra, Calculus, and Geometry handled. Beyond that, advanced math classes are used to weed out the retards at a college level. Which is pretty gay if you are a college kid who hasn't figured out a major yet. :geek:

From what the boys at Stewart & Stevenson in Denver were telling me, there is a huge amount of money to be made in the oil fields if you're a smart. hard worker. :thumbsup:

= (-5 squared is 25. 10 times -5 is -50. 25-(-50) is 75. 75 + 5 = 80)/(-5 squared is 25. 2 times -5 is -10. 25 +(-10) is 15. 15 - 1 = 14)

 

80/14= 40/7

 

Edited.

 

Holy crap, I can't believe I messed that up. I guess that's what I get for drinking a few beers and trying to do some math.

......................just keep asking questions. IMO that's the best way to learn fast.

 

As a manager of sorts, I am constantly keeping unofficial score for the guys that work for me or with me. The guys that ask the most intelligent questions at a reasonable volume tend to also be the best guys I have. Sometimes it takes alot of drive to be the guy that stands up in front of folks and asks a question.

 

It's the guys that don't ask and do something anyway that I wind up wanting to choke a little bit. :down:

I grew up outside of Detroit and I thought that too. But I tell you what, every time I smell that sweet Detroit funk, it smells like home...

Interstingly enough (or maybe not), I just had a similair converstation comparing towns with a girl in Detroit. It basically wound up that Portland and Detroit both smell. but the bms in Portland would definitely lose in a fight with the bums in Detroit. :biggrin:

Never been to Portland, so I can't say. The farthest west I have been would be St Louis. The Detroit bums are pretty hard core. They would kill you for a 40 oz in a second! One of many reasons not to go down town...
