What parts of Algebra II are essential to learn?
Q. I'm teaching myself Algebra II- I just want to know if there are any parts I should skip, and, also, what parts are key to really know well? I know ideally all things should be learned, but I want to get what I need to know so I can move up to Calculus. I'll also take a class in Algebra II to master what I've taught myself. This way I can move up faster. So what do I need to know, and what can I skip? Thanks.

A. Skim the chapters, if it looks like you know it, then read it but don;t study or do any problems. If you odn't know it, do whatever you do to get it down. Good luck, you seem smart =)

Which is the better math to take after Algebra II?
Q. I am in the 10th grade and taking Algebra II. Which math should I take as a junior and a senior?
Asked by MORG225 - Thu Sep 28 18:19:52 2006 - - 13 Answers - 2 Comments
A. I don't know how different school label their math programs. I just remember math as: Algebra 1,2 Geometry Algebra 3,4 Math Analysis Calculus I don't know what "math analysis" is at other schools. I guess it's like trig. What math did you already complete? Most people are suggesting geometry/trig, so I guess if your Algebra II is the equivalent to my Algebra 3,4, trig and calc would be the answers.

Can I take Pre-Calc Honors with minimal Algebra II knowledge?
Q. If I only know the basics of Algebra II and forget like half of it, can I still do well? Or is Pre-Calc on a whole another level than Algebra II? Will I need to know Geometry for Calc or Pre Calc?
Asked by 3060903Angle - Thu Nov 13 20:22:02 2008 - - 3 Answers - 0 Comments
A. From my teaching experience, I know that most pre-Calc courses go through a review of Algebra ll in one to two weeks. Then they switch to trigonometry and Analytic Geometry. In an honors class they will not review algebra at all. That means that you have to be able to, among other things, solve systems of simultaneous equations, solve quadratic equations, and solve word problems before the first day of class. From what you have written this does not seem to be the case. For any pre-Calc course you will need to know: 1) Algebra 1 2) Geometry 3) Graphing techniques For any Calculus course you will have to know: 1) Algebra 2 2) Geometry 3) Trigonometry 4) Graphing techniques

A. Let the two consecutive integers be x and x + 1 x^2 + (x + 1)^2 = 25 x^2 + x^2 + 2x + 1 = 25 2x^2 + 2x - 24 = 0 x^2 + x - 12 = 0 x^2 + 4x - 3x - 12 = 0 x(x + 4) - 3(x + 4) = 0 (x + 4) (x - 3) = 0 So, x = 3 and x + 1 = 4 or if the integers can be negative, x = -4 and x + 1 = -3 Both are solutions.

I need help in Algebra II. We have to solve the problem by writing a compound inequality. Help?
Q. A Baker needs between 40 lb and 50 lb of a flour - sugar mixture that contains ten times as much flour as sugar. What are the possible weights of flour the baker can use? Help now, would be appreciated.

A. Let s and f be the weights of sugar and flour in the mixture. Then we can write an expression for the total weight of the mixture: s + f. Also, we know that f = 10s or s = f/10. Now, we can rewrite s + f as f/10 + f = 11f/10, and insert it into a compound inequality: 40 11f/10 50 400/11 f 500/11 So, the baker needs between 36.36 and 45.45 pounds of flour.

What should I know from matrix algebra for the Praxis II Math exam?
Q. How do they test matrix algebra on Praxis II math in multiple choice format? This is for the exam for potential math teachers.
Asked by Allison - Thu Mar 20 09:48:12 2008 - - 1 Answers - 0 Comments
A. Know how to calculate the inverse and determinant of a 2x2 matrix by hand. Know how to multiply two simple matrices by hand, and know that matrix multiplication is not commutative. Know about elementary row operations and how they relate to solving simulatenous linear equations and how they relate to inverse of a matrix. Know the relationship between no unique solution to simultaneous linear equations and no inverse. Know how to use a graphing calculator to calculate the inverse and determinant of a 3x3 matrix. What can they ask in multiple choice format? Given a 3x3 matrix, find the first row and first column element of the inverse. Good luck!
