How does this new math work with traditional math formulas for Algebra and Geometry.

Math is math. Old math, new math, whatever.
Common core uses the same formulas for algebra and geometry but it takes it a step further and tries to give a little understanding to what those formulas actually mean in the context of a problem.
I'm in my third year of teaching 7-8 math at a VERY small school and we are getting into the TNready program (common core with another name). It makes the math a little more challenging because it makes the student think about the WHY.
Anyways, I enjoy it and think it's a good thing. There are ups and downs to everything.
I sent a letter to his teacher asking the answer and how it was reached. We never got a reply!
That Common Core Crap has no Common sense.

I used pi once to calculate the c.i.d. of an engine

Yep, same here. I do use pi quite a bit calculating stuff, so I suppose that might be algebra on the baby scale. As far as those equations that are two feet long, and contain half the alphabet, that's just nonsense.
Once I escaped GOVERNMENT schools, I excelled in Math. Basically started from scratch in college and completed up to Calc III with 4.0s in Math and Science.
I have lived in enough different states and am all too familiar with how lousy a job GOVERNMENT does in telling states how to teach math.
Just by noticing that another day has passed and figuring out what day of the week it is, you are using algebra.......
How about pumping gas? If you pay 2.37 a gallon,and know how much it costs to fill up your vehicle, you are computing the number of gallons you used. (don't tell me you guys don't reset your odometer to find out your MPG each tankful) Y=2.37X is a simple linear equation that can be graphed and made into a simple X and Y table. You should see the kids' eyes light up when we graph it.
Just a few examples of using algebra every day.

As a matter of fact I don't reset my odometer when I fill up.
I just grit my teeth, pay the man for the gas and carry on.
Sort of an "out of sight,out of mind" kind of thing.

Alright, do you recognize that you are paying money for that gas and also realize that it is subtracting from your total amount in your checking/savings or credit card limit? Algebra

Call it what you want, Rob. to me that is just add/subtract/multiply/divide....I don't need a fancy name for it.
Yes, I also know how to figure out square feet, cubic feet and other things.
This has nothing to do with common core. NY schools have taken a simple math problem and made it into an 11 step clusterbleen. THAT is the Common Core stuff we are talking about.
A pound is a pound the world around.
Well, it used to be anyway.
I also enjoy cake fairly regularly.
A pound is a pound the world around.
IIRC the actual saying is "A pints a pound the world around"

math is math. starts with 1+1 and goes from there. it just gets more complicated and you learn more things you can do with it, solving different problems.
there is a large body of accumulated "math" knowledge. math is math is math. it just is. only thing that could be different about this is what they teach and how they teach it.
do they leave out stuff? do they try to emphasize more practical things to use?
I don't see how it could be any better. only simpler, and dumber. maybe better if that's what simple people use but they are only missing out, especially the students that go on to higher studies.
the teaching of math was meant to make you learn how to think. if what you are taught is dumber and incomplete, then how you think is dumber and incomplete.
it is a fact that since the 70's schooling was geared to make people work better together. this "common core" crap I think is geared to make people work and think like unthinking worker robot peons under corporations and subjugative political schemes.
we always have been treated as economic cattle. now the system wants to actually grow us that way.
