I am looking for a math handbook that was given to me a million years ago to give to someone. As I am looking for this book, with no luck in finding it, I came across an Algebra textbook...

I am posting a few problems... So here they are:

Problem 1: Evaluate 2/3[8(a-b)^2 +3b] if a =5 and b=2

Problem 2: 5(9+3)-3*4

Problem 3: Evaluate x^3 +5(y-3) -xy
if x=2 and y =12

What's your answer?

Who really cares! All you need to know is 2+2= 4, and 3x 3= 9. That way you can balance you check book and not run your farm like the crazy are running the goverment in washington.

I agree with the government thingy there jdm.. But...... Sad That is certainly not the attitude we need toward math as a whole.. But maybe I see where this I don't need to learn math attitude comes from with the kids now days in school... I guess that who cares attitude is why my son tutors math kids in college ( ten last semester) who don't have the skills to make it in a college... All I can add to this is without this math your john deere or any machinery wouldn't be what it is whether you like it or not.... And remember everytime you sit your butt in a tractor of any kind it's young men like mine who are designing and troubleshooting the machinery..... Have a good day!! TipHat Wave

A few more interesting problems that we can try:

1. The base price of the 1991 Buyer's Car of the Year was $15,925. The base price of the same car in 1994 is $19,705. Find the percent of increase.

2. Connie's clothing prices their goods 25% above the wholesale price. It the retail price of a jacket is $79, what was the wholesale price?

3. Delectable Dan's Cookie Company sells two kinds of cookies daily: chocolate chip (yummy) at $6.50 per dozen and white chocolate macadamia at $9.00 per dozen. On Thursday, Dan sold 85 dozen more chocolate chip than white chocolate macadamia cookies. The total sales for both were $4055.50. How many dozens of each were sold?


Maybe we can help each other solve the cookie problem?

Hello TB,
I getting ready to go back to school next Monday to finish my last two classes. My last class will end on April 30th and I go back for graduation on May 24th! The worst part seems to be over, just working on my capstone project. Hope you'll have a blissful, healthy, and prosperous 2012.

We need our kids to get more involved in the sciences and mathematics so that we can continue to move our country forward. Maybe one of the factors that our debt is so high and we can't seem to reduce it or account for the interest rates we are paying to China is because our politicians signing the bills only know "2+2 =4 and 3X3 =9".... I value the basic mathematical foundations, but that's not enough if one wants to graduate from high school nowadays.

My intentions of posting these math problems was not to make you or anyone angry, but rather to make them available to solve them. It is essential to do things like this to keep our brain active in different ways...

Hope that you'll have a great 2012.
